ts true!!
if he adds stickers on the doors it will give him another 30bhp too
am I the only one here who thinks that this might be possible depending on the car?
If its manifold, decat and exhaust its potentially feasible that you might get near to that if the stock system is appauling... and 30bhp from a remap that ups the boost if its a turbo could be achievable.... maybe?
thought so... so obviously we are now required to know what car it is....


Wish I could double my BHP like that. He'll get up to 5bhp more.
He could loose power if a proper remap wasn't done and the exhaust didn't provide enough back pressure.
Tell him to fold down the back seats for +5bhp too![]()

If you fit an exhaust that is too big you actually create more backpressure.
Engine's needing backpressure is a myth.
