1998 Trans Am LS7 with Procharger 10 to 11 PSI peak. Thoughts about some fine-tuning
First time I've been able to tune consistently because it broke every 4L60E or build I put in. Now that the 4L80E is living, I got some hurdles.
1. I got some LTFT's going into WOT
2. Tip into boost always hits lean for a moment
3. 50 to 60% throttle (close to boost) was rich 10:1... I began to get away from that, but still struggling
4. I usually have KR in 1st gear, but barely any when rolling and hit from 2nd gear.
5. I finally got more consistent mid 11's for AFR. It seems to like mid to upper 11's.
6. I change from dual Walbros to single Hellcat and upgraded Boost referenced FPR with bigger bowl and 8AN return.. and 8AN Rails
Any advice would be appreciated. Here is some data.
