this is not pushing it in my opinion... if I was running the wrong gear and running 20psi to make this power I would consider that pushing the limits. I have found a kit that works, and works well!!! It does not get driven on this tune everyday!! This would be a drag/dyno only tune!! Anyone with a standard engine would be mad to run around risking their engine and 400rwkw is useless on the street, even my daily 370rwkw tune is useless!!! and no dillz, no atomic engine on layby yet!!! I havent achieved my goal at the drags on my standard engine and turbo yet!!!
