Dennis,
I have a FAST system on my Grand National and I love it. The Wide Band is very very handy for getting dialed in. For example, I have bascially two programs that I can load into the ECM. Program one is set for kill. 32 PSI of boost. Program two is get in and drive home while still pulling 28mpg on the way. It is very easy to use, easier if you have someone that can run the laptop while you drive around. If you get to that stage, I have some friends that are FAST wizards and can help you with the tune.
Also, I am a little biased. The guy that built my GN engine is also the senior electronics systems engineer for FAST. He does the designs for the ECM. Also, check out
www.hartlineperformance.com for some info. This is a friend of mine in Florida that tunes FAST systems. Notice the Cobra he tuned on.
Hope this helps!
T.
