The V8 motors used in the GT changed in 2005. They went to a 3 valve versus
2 valve engine. They also increased HP from 265 to 300. The 2003 GT has
265 HP.

Completly differant. You should rent another one for a week end. The V6/Auto is
an excellent combo. It's a 4.0L detuned V6 mod motor. Same as the V8 but with two
cylinders lopped off the front. It's detuned so it doesn;t compete with the GT.
With some very simple changes you can get GT performance.

Salesman in my are are really dealing on the V6's. A V6 auto is about 10K less
than the GT similarly equipped. And you'de be surprised how little power differance
there is between the two engines.

Yea it sure is!
Now I understand why my dad wanted to buy that VW Karmanghia Vert. when I
was growing up and he was in his late 40's.
I didn't understand it then, but I sure do now!
> Me neither! What a pig. Very uninspiring styling, too.
Yea, the car was yellow and a vert so that sort of made up for it, but the
3.8l motor was a pig.
I drove it for about a week as a rental.

I'd love to but it's very difficult to get them from Hertz.
I rent a lot of cars, due to business, and my company is one of Hertz's
largest customers and even *I* have a tough time getting one.
I was pretty impressed with the 2006 I rented. It was a vert, had the pony
package but no interior upgrade package.
I've basically figured out I want Vista Blue with the Pony Package mostly
due to the suspension upgrade and also the interior upgrade package.
I will need an automatic as well, but that's about all I need to keep me
happy.
Are there any other options that people find are "must haves" ?
I'm trying to find a 2006, but that doesn't look good so I'll most like
order a 2007.
Also the warranty increased for 2007 I believe which is a plus.

Any pointers?
I've read about the EPROM flash to get rid of the torque limiter and I
suppose a decent cold air intake might help a bit?
Yes/no?
I don't like KN stuff because of the oil and MAF not playing well together
over the long haul.

Yea it does.
Especially with a rally stripe, but I've heard of horror stories so I'm
not sure about that one.
Also, the vert is a vandalism target and even though I live in a peaceful
area, you never know who you might piss of :(

Yea, it gave me a bad feeling as well.
I ran a Carfax on it and it had 3 owners in 3 years, not that Carfax is

I have a test drive set up for Sunday so I can compare the V6 and the GT
one after the other.
The salesman said pretty much the same thing you said BTW, but I asked him
to humor me ha ha!
I'll report back to the group my impressions of both!

Hey! I know that guy! LOL!
Just a couple of comments...
Yes, reprogramming/re-flashing/re-tuning a V6 autotmatic makes a HUGE
difference... It is truly a night and day difference! I mean you will
not believe you are driving the same car!!! The Torque Limiter really
kills the off the line preformance of the V6 automatic... It is the
best $400 you will ever spend on the car! LOL! And it is incredibly
simple to use! Just plug it in, follow the on screen instructions, hit
a button or two and your done! Need to take your car in for warranty
work? Simply use the "Return to Stock" option! It really is that easy!
The tuner/programmer I recommend for automatics is the SCT X-Cal2.
There are a number of good shops out there selling X-Cal2 but for an
automatic I highly recommend Lidio at Alternative Auto. Here is his
write up on his V6 tune:
http://www.alternativeauto.com/prodserv/v6_05mustang_tune.html
Take a look at the gains he got just from his tune:
http://www.alternativeauto.com/images/05mustang_v6_dyno.jpg
Especially look at the low end torque gains! LOL!
Now the other think you asked about is a CAI... Most all of them are
going to use a K&N type oiled filter... there are a couple of "dry"
filter kits out there but I really don't know much about them. I've
been doing the oiled filter for quite some time... key is not to over
oil them... But actually the stock air box is not that bad.... it
actually does quite well until about 4000 RPM..
The other mod I highly recommend is getting rid of the stock muffler!
It is horribly restrictive! You can pick up 10RWHP by puttting a good
after market muffler on! You can even put a GT take off on! (The
10RWHP was documented by Justin at VMP Tuning on his dyno... I am not
making the number up! LOL)
Good luck with you new Mustang, which ever way you decided to go! Keep
up posted! LOL!

I notice that with the XCal I believe you need to run at least 89 octane
gas more than likely because they play with the timing curve and or knock
sensor.
Is this true for everyday driving as well, or just if you are
really nailing the throttle?
Do you know if they are bypassing the knock sensor with the program?
I would guess if not, you could run 87 and if it pings the knock sensor
would retard the timing?
TIA

Old stuff, old tuners trick, they are uping the timing, engine runs leaner,
puts out more HP, but requires higher octang to keep from detonation.
not a good way to get real HP. They got 20 more HP ? can't even feel
that.
What if your old lady puts a tank of 87 in it, or that sandnigger switched
gas on you and you think you are buying 93 but it is really 87 ??
you gonna limp home.

To bad you don't know what you're talking about... The new Spanish Oak
has a Torque Management System that will kill the the car's performance
off the line... If it decides you are trying to make too much torque
it pulls timing, etc. and gives the car a very sluggish feeling off the
line..
Lidio (along with the other tuners) will all supply you with an 87
octane tune...
As far as not feeling it... There is a huge jump in REAR WHEEL Torque
that I you WILL feel...
As far as leaning it out... Lidio tunes for a very acceptable 13.0...
http://www.tammyandjohn.com/Mustang/Screaming/Images/cnl_dyno3.jpg
Perhaps you need to brush on on the NEW stuff...

My mistake... the way you referred to "leaning it out" kind of made me
think you were referring to shops that will lean a car out too much
just to get the additional power. Lidio tunes for a safe A/F ratio..
So yes, he leans the fat factory tune out some... but he keeps it safe
at 13.0...
Terry Brannigan - 21 Aug 2006 01:12 GMT
> Old stuff, old tuners trick, they are uping the timing, engine runs leaner,

Of course, but how does the engine management system deal with it?
IOW let's say the Xcal curves are more aggressive, if the knock sensor is
still in the circuit, running 87 should cause timing to decrease if the
engine is detonating, but will allow full performance with 89.
This is highly simplistic, but as long as the knock sensor has not been
disabled and the timing curve isn't way out of limits, the knock sensor
should do it's job and allow "normal" around street driving on 87.
> not a good way to get real HP. They got 20 more HP ? can't even feel
> that.
I disagree.
You can easily feel 20hp.
Also the V6, at least from my 1 day driving trip, DOES have a throttle
lag, bogdown, whatever you want to call it, from a dead start.
If the Xcal gets rid of it, just that alone will make a BIG improvement in
the overall drive-ablitly of the car.
> What if your old lady puts a tank of 87 in it, or that sandnigger switched

Not a chance.
First off, the knock sensor will still do it's job.
Second, a little pinging isn't going to kill anything dead on the spot.
Just back off a little on the throttle and all will be well.
Haven't you ever gotten *bad gas* ?
I have, and my cars typically ping like crazy until I toss some drygas or
fuel injector cleaner into the things to purge the crap gas.

That is EXACTLY what an X-Cal2 will do for you!!!

Ok... first a disclaimer.... I do not work or speak for any given shop.
I will simply tell you what I have learned from working with them...
What I am about to say I believe to be accurate but again, I am not an
official spokesman! LOL!
First item: Knock sensors. Most tuners will leave them on. I know
that Lidio definitely does! Acutally the Spanish Oak will try to ADD
timing if it feels the car is "under-sparked". Like I said though...
Lidio leaves the sensors enabled..
Second item: 87 vs 89 octane. I think Lidio might actually have an 87
octane tune. You might want to confirm... or ask for one.. but worst
case scenaro... you can adjust the timing in the tune right on the
X-Cal2! When you go to load the 89 octane tune you can simply pull
some timing... Very simple to do!

Go down to your local book store and pick up a copy of Mustangs and Fast Fords.
Lots of advertisers in there.
Simple things will make a big differance. Cold air, computer reprogram, lighter
drive shaft, better tires, lower gearing, etc. Standard hot rod stuff we've been
doing to Mustangs for decades.
K&N stuff is OK. It's been a standard of the industry for a long time. I have
K&N filters on a number of my vehicles. But I think there are now some better
choices available for specific applications like the Mustang.

I went from a 130K miles 1995 V6 Coupe Mustang to a 2005 V6 Convertible
Mustang. I too can get x-plan. But my budget allowed for a v8 coupe or
a v6 loaded convertible. A while back I had a 2005 V6 coupe rental for
about 2 weeks and put 2000 miles on it. Just fell in love with the
handling. It is vastly better than my 1995.
I got luck and wa sable to keep control and play one dealer against
another as both wanted to get rid of their $32K 2005 sticker V6 Premium
convertibles in March 2006 with the 07's looming. I ended up paying 23K
out the door for this car where a comparable 2006 model would have been
about 30K out the door with x-plan. No 2005 GT's left anywhere so no
dealing on those.
It's been 5 months and I love this car. the 200HP v6 is more than zippy
enough for me although I would have preferred a manual over the auto
transmission. As it is, I'll have this baby paid of in 4 years with a
FMC .9% APR finance deal. Making it more profitable to leave my money
in the back and not even put anything down.
It's the time of the year when you should be able to get some deals on
2006 models with the 07's coming in.
Happy hunting and do your homework so the dealer doesn't screw you.

Actually the V6 is 210hp and 240 ft. lbs of torque. About the same
horsepower and torque as the 68 Mustang with a 289 4v, not the HiPo version.
I opted for the V6 and options as opposed to the V8. It wasn't worth the
extra 7-8k for 2 more cylinders. Not to mention I saved a little on
insurance cost with the V6. I've had my 06 now for about a month. I enjoy it
and have no regrets.

It might be making near the same published power and torque, but with a what

What about it? Doesn't change the fact the motor is still puts out 210hp
stock.

I'm old enough to have driven the Dusters, Challengers, Chargers, Nova's
etc of that era, albeit in the 70's not the 60's, but one thing springs to
mind when I remember those cars:don't try and take a corner at speed.
Skateboards with rocket engines on them.
The suspensions on most of those cars was terrible, some would say even
dangerous.
Add in the bias ply tires, or first generation radials and you were
looking at some seriously compromised cars.
Sure they could be modified but out of the factory that DC torsion bar
system was a mess. GM wasn't much better with undersized components.
Those cars were designed to go straight line and they did it very well.
Just don't try and turn a corner :)
They were a hell of a lot of fun though, and still are!

always a joy traveling across a steel grated bridge..
