If it's not coming with one you will likely need a bored out
throttle body to handle the air. You could use a boost-a-pump
unit to increase fuel pressure or an adjustable fuel pressure
regulator on the rail. Increasing fuel pressure does the same
thing as larger injectors, it's your call. I'd probably go with
larger injectors and the stock MAP.
Might ask the Yahoo strokers group.

Check the Yahoo Strokers group for some recent feedback on Titan. Also
look at Golen as another alternatives. Lower temp thermostat, free
flowing exhaust, larger TB, 24 LB injectors, adjustable MAP sensor and
an adjustable fuel pressure regulator are all reccommended and probably
required to run pump gas without pinging.

The injectors are on their way, I have the parts for the MAP sensor,
and a thermostat sounds like an easy swap. But for the cost of the
exhaust, TB, and AFPR, I can buy a lot of premium if I have to ...
