I was doing lights and my sub and disconnected the battery, and was like F@$K!! I remember hearing if you do that it erases your tune. Anyone sure about this or can correct me? And another thing...I can smell gas burning after I get on it thruough a few gears and actually saw something on my friends windsheild after he drove behind me for a while, anybody know what that one is either?? Thanks in advance

 

No, tune is still there.

The tune is there...but idk about the gas thing

 

leaky injector, maybe unburnt fuel coming out the exhaust. when i had an injector leak it drained down the underside of my car and then sprayed off the transmission and onto everything behind me....it was a bad leak

 

yeah im pretty sure its unburnt fuel because it smelled exactly like gas. howd you fix it? and thank you i didnt wanna have to get it retuned
