Hello All. I finally gave up and gave in with this fitech issue I am having. Setup: 5.7 V8 - Stock w/ edelbrock intake Turbo Charged - 10 lbs. boost Issues: after acceleration and on deceleration from cruising or WOT, AFR goes way lean (16.0 -20) and almost dies. Seems to happen more dramatically under hard braking. When I shift into gear from park to drive or drive to park, seconds later, I will have this same lean spike and the engine almost dies. I have talk with the tech guys at fitech and after trying what they had advised, it made the problem worse. They think its getting too much fuel and the system overcorrects. However after doing what they said and nothing changed, I lost interest in talking with them. I have been working on this problem for about three months trying all sorts of things from the forums across the internet with no luck. Any advise with be helpful.
