So my car runs tits on WOT within 2-3% of WBFactor on SD. The problem I'm having is when accelerating or WOT at 2400rpm to 3000rpm I lean out to 18afr then drop back down to 14afr before heading into the 13s. Everything in the log looks perfectly fine no spikes or knock. Afrest is on point but just my AFR leans out. No maf or exhaust leaks or boost leaks. Whats an idea that could cause this. I will get a log in here asap.
 
I can't view your log but I'm 100% sure it's the tps delta...it's under throttle tip in in the da area. I already increased each value by 15 in some areas but tps delta still spikes on my log in some places. I'll be increasing it more today for better results.
