Hey, was looking around this site and see that alot of people no there shizz about astras!!
so anyway i was wondering if some 1 could help me..

ive got a Astra 1.6 sxi 16v twinport, what is the bhp for this

im taking my car for a stainless steel cat to back in 2weeks with also a Viper induction kit ordered with cold air intake, what added bhp am i looking at here?

and next on my mind is a ECU Remap, what extra BHP would i get from this and would it be worth it?
thanks, grindle
