something just seems off to me and I cant figure out what it is. everything I seem to adjust doesn't seem to do anything. cold starting and backing out the driveway if I blip the throttle it will want to die or even sometimes die. driving down the highway today it was running good. on my way home it was running rough down the highway I have no idea whats wrong with it. it was tuned but not by me and will not say who tuned it either. it has a circle d stall 258mm single disc, milled heads .035 stock thickness head gaskets ported intake and TB roto fab intake with ls7 maf e85 flex tune but currently been running just 93 with decapped stock injectors long tube headers cam is a 22x-23x 111+2 lobe separation angle.
