Vortech Installed. Bad tuner?
I guess I'm looking for input from other vortech guys on here. I installed a V1, non intercooled, 8lb pulley. 42# inj, 90mm MAF, etc, etc. I have all the supporting mods I need and dyno tuned by reputable shop. I've put about 500-1000 miles on it but have a few concerns:
1) It MUST warm up before driving. If i try to start it and drive, it will stutter, spit, and bog until my coolant temp reaches about 100. It idles great in the meantime.
2) After releasing the throttle A/F drops down to 10-11 for about 3-5 seconds which feels like it's flooded when I go to accelerate again. Meaning that the car feels a little bogged down afterwards for a few seconds till it clears out.
3) After a partial boost acceleration, I seem to have a small amount of detonation/backfiring on decel.
The car drives amazing at WOT and idles perfect. It seems to be that all the in-between stuff messes with fuel delivery sometimes, but not always. Any experience with these problems? Think my tuner just didn't do a great job? Maybe partial boost can't be tuned for? Any input is appreciated, thanks
