Got my car set up on e-85 on 5 lbs of boost and im having an issue of breaking up, it will happen on one WOT pull and not on the next. AFR while its doing this looks good and so does the timing. it its like hitting a wall. Im logging the basic stuff but what else can i log to see whats going on? its a 3 bar sd (no Maf) OS with PE disabled for tuning. Ive read that logging CYL_DMA may lead to some insite.
Thanks
