I guess I'll take that as a half assed appology. Ok, help me understand one more thing, and thank you for helping instead of just being an asshole, appreciated, why is my car faster, and the dyno curve smoother and more powerful? The mixture is leaned out. Unless the tuner reprogramed the VAFC, and now it says - when its + and + when its -. I guess I dont understand how I could gain anything, you would think if I fucked up the timeing, I would lose power.

Snoopy, does that happen even with a very small amount of fuel trimming, or is it more of a factor when boosting and you adjust your fuel trim A LOT?
