I have what u call.... A PROBLEM!
Went to go time my car tonight with the G-tech and these problems happened.
#1. Lined my car up, went to floor it and I saw an explosion of fire inside my open element and the car instantly stalled out. But it started right back up and ran like it did before, but it has been doing that on and off lately and its only when I floor it or give it 3/4 throttle from idle.
#2. Lately I have also been hearing a ringing at idle. Maybe it rings at higher speeds but I can't tell because of my exaust noise.
#3. When I am G-teching the car, it seems to loose power at around 45mph. I am thinking maybe my fuel pressure needs to be boosted because there is more air coming in that 14x3 open element from my ram air hood, but its just a guess.
SOOOO...these are my problems. Is my timing bad one way or the other? Thats my guess. I would go in the garage and check my plugs but the garage is full right now.

My throttle body would set on fire also when my fuel pump went bad and i wasn't getting enough fuel. This usually happens becuase of a lean condition so i would think that you need to increase your fuel pressure. You've already opened up your exhaust and intake, so a little extra fuel would be good, i think.
