my cars tends to knock or sputer a few times when i get under 1,000 RPM's i think it has something to do with the tuner i just got a few days ago, it has only been doing it since then. could it be my air/fuel ratio? or is there something really wrong with the engine?

i feel like im killing my stang:deadhorse:yes it was the defualt tune of 93 preformance but it only had 87 in it, which explains the sputtering in low rpm's-not a high enough octane level in the gas. i retuned today it to 87 preformance untill i use it all up, then im going with 93 octane and a 93 tune and i'm going to see if i can feel a difference...

You will feel the difference. Detonation is very bad........
