Plain and simple, I was getting on it and shifting hard from 1st to 2nd. This has happened twice and what I have heard sounds like a gasket on the exhaust blowing out, but best I can tell everything is fine. First time was my fault for getting on it hard on purpose to see what it would do, the second time was to get out of the way of another car that was running a stop sign. I don't want to hurt my car, so I would like to know what it is capable of doing and if this is normal or not. Does anyone know if there is any kind of back pressure value like a BOV on a non-turbo setup?
Never mind, someone else started a new thread on a similar topic that I have gotten my answer from. http://www.lancertuners.com/modules.php ... highlight=
