i've been slowly getting my VEs in line (i think) using my wideband and HPT. i noticed that my stock tune had a fairly nice, smooth VE but when i'm trying to dial in 14.7 in all my cells the closer i get the choppier my VEs look. is smoothness or acuracy more important? are resonance in my changed intake and headers to blame making certain RPMs and MAPs more pronounced? also my LTFTs are turned off and i set my ECT vs IAT to 284* to force open loop, do i turn off my STFTs also when logging?
