just a query regarding a decat i had my car mapped then tweaked for air box mod then did more inc 3" turbo back i need a tweak for the cat removal but when ya give it beans as you lift off and press the clutch it seams to over rev briefly like ya blip the pedal as you lift off if it make sense i guessed it was cos i needed a tweak but just watched "josh" on cadwell park on you tube and it seams to give the same grunt after lift any one else have this ? is it a decat trait?
