Tune or converter problem or? Long story short, finished swapping my lq9 last week into my 06 single cab sierra, mods are circle d 3000 stall, longtubes, and a tune with a stock 4l60e (besides corvette servo). Truck is tuned, and runs great, but noticed something weird @wot. Idk if its a trans or something else. Basically if I lay into it, the motor will flash up, run till about 4700ish, fall back to about 4500rpms, then keep pulling. It doesn't like fall flat on its face, but its like the throttle backs off for a milli second. Let me know what you guys think, I hope the video works decent.
