I presume you mean the Performance Package. The sports package
is seats/wheels&tires/trim. The difference between PP and normal
cars is just some tweaks to the ECU AFAIK.

Thanks. That's exactly what I was thinking.

In which case it's funny how Dinan claims that the OEM software has "left no
horsepower for we tuners to extract", yet BMW comes around and pulls out
10hp more...

Of course, no one knows this programming better than the manufacturer, so
it's not all that surprising that BWM could do it but a tuner couldn't.

Cheers,

Pete

Yes, but they added more than a chip. Dinan claims no hp gain, Conforti
about 3hp (or 6 with CAI), powerchip around 13 (with 93 octane) .... hmmm.
