Hey everybody, just got done tuning and everything went well during. I set the boost at 15 psi, cruise afr is between 14.5-14.9. When I initially tuned my wot I had a solid 11.1-11.3, ran great, decided to be safe and took a couple % off to get more in the 10.8-11.1 range.
After I made those adjustments under wot the car started stuttering at 3-4k and would drop to 12.5-12.7 afr.
I tried reverting back to the other values (had them written down) and now it does it with those settings too.
Already read through some stuff and found when you start going past stock boost you need to gap the plugs around .020, I have done that. Base fuel pressure is 43, wally 255, fic 650 injectors. I don't have a log and I'm at work so I can't get one till tomorrow...
Any thoughts on this?
Also, the last adjustments I made and did a pull the motor bucked and I thought the thing was going to drop out of the car... so I don't even wanna drive the damn thing
One last thing. My wideband is 4" upstream from the cat, my afrs are showing "normal" but my safc is only tuned at the most -8... with 650's... shouldn't it be in the -20's? Possibly more???
