Anyone gone from Stock pcm tuning to the F.A.S.T system

[95Bird]

I've heard that just making the switch has needed some gains of .25 and 3 mph. Anyone else experience a difference with no other change. What do you gain with the fast system over our current system with lt1 edit?

Thanks for the info guys

I honestly haven't started tuning mine yet, but heres a rundown for ya.

Wide Open throttle will almost tune itself. With the Wideband 02 (A MUST have!). In closed loop the PCM adjusts itself to the designated A/F Ratio. You still need to tune it so that the PCM isn't doing much adjustment (Within 5% or less).

-Full Datalogging of designated modules...
-On the fly tuning, No waiting while
uploading a flash
-And obviously the reason you're looking at
it, the ability to turn >7k rpm

Theres SOOOOOOO much more to the system though.
