Hey All, this is still an issue for me. Ive run a couple tanks of gas (93 octane of course) at various speeds and drive times and its still pretty bad - I figured it would eventually work it out - Wednesday morning while stuck in traffic on the long island expressway the sputtering actually had my truck bucking while i was just touching the gas, it felt almost as if my truck was a stick and i wasnt giving it enough gas. I am also noticing that from a rolling start (under 25 mph) the sputtering occurs on light acceleration up to almost 2200 RPMS. I cant drive my truck stock anymore so if anyone knows what the problem could be please keep me posted!
Thanks so much!
Side note: My buddy suggested that it could be the transmission settings on the canned tune - he said something like maybe its too much pump pressure at a low idle? Does that make sense to anyone?
