Ok stats are ls2 402 stroker, t56 trans nitrous cam 614/621 227/235 113+3 stock heads 1 7/8 longtubes. stock ls2 injectors reflowed to 55lbs from fic. Car runs great cruising around 14.6/15.2 afr around town and highway, wot 12.30/12.70 afr. Tune is running in maf mode only open loop. Trims are disabled. dfco is disabled, not every time but more than a few times the car after going wot when im letting off will go super rich, like 9.0-10.0 afr then super lean 20-22 afr. The last time this happened it spark knocked like crazy. I will upload a tune file and a scanner file later, does anyone have any ideas? It seams like after going wot if i stick the car in neutral I can duplicate the issue everytime
