I have a 1.7 cdti astra mk 5, i have debadged it and put a sports frile on the front, looks pritty mint, however, could any one tell how to improve its speed, it is already chiped up, and leave 2.2ltr dielels in the past, but want more power.
I have the astra mk5 1.9 CDTI X pack, re-mapped to 190bhp (stage 1 re-map takes it to 190bhp) upgrade ur engine and re-map it, if u want to stage 2 re-map it then you should start changing the turbo,oil feed,gaskets etc
