(It did do 314kw, but detuned it.) I got a 100cpi racing cat of rapid (Chris) and fitted this in with the 3" exhaust. Sounds beefy :-)This is about what I wanted for this tune. The car has standard auto 4 spd, so don't want to blow it up just yet :-) The guys at C & V said that the car just wants to make power, but not having fuel pump done restricts me a bit also.

I have bf mk2 so hopefully with 2nd cai, bigger cat, injectors & tune I should get close. I'll keep an eye out for a cat back exhaust.cheers Link to comment Share on other sites More sharing options...

Wish I could afford to do mine :-)You have the ZF auto so you have no dramas there. IThere is x-force mild steel exhaust on ebay, can't vouch for them though. It would nearly be worth doing the cat back when you put the bigger cat in :-) Link to comment Share on other sites More sharing options...

I make just over 300 @ 12PSI due to 4" dump and twin 2.5" system. Only thing that will be holding you back will be the cooler for high 200's. I had a monza, and when I changed tot he HDi, I gained 30RWHP from the same tune.Good luck modding it's infectious and you will be hunting for 400RWHP (300KW) before you know it Cheers,Ben Link to comment Share on other sites More sharing options...
