car runs fine just don't know if there's something I should do to protect it a little more before getting a proper tune. Only thing it does different from stock is after I've given it a bit of juice, while on deceleration if I tap the throttle it'll BANG!! But that's it. Any feedback would be sweet. Cheers.
