Hmm alright. Well the stupid thing is that that stock tune is installed and the only thing dif is shorty headers. But now the problem is that it surges, but it surges lean which makes it run better. How the heck that happens idk. Cause itll go real fat then it sounds like its got some ***** behind it then it goes fat again.
