iv'e been going hammer and tongs at tuning me astra up recently (iv'e had the car for 5 years n she's been a trusty war horse but i was a tad bored!)
im sitting on a standard set of cams till i have the pennys...(holiday coming fast and im getting the timing & balance chain done up wit Daz, so savings are stretched at mo)
i also need to try n pick up a piper 4 branch probably in the new year,
what i would like to know are there any small tips ive missed out along the way?
so far ive got this done;
1 piper cross viper air filter
2 diblas flowmaster extra wide inlet/cold air feed + 3" ducting
3 heavily ported n polished throttle bodys(top flange is to a knife edge n she gleams!)
4 blanked egr valve(yet to get a cheater)
5 200 cell sports cat & powerflow cat back
6 2.4 chevy manifold
advice greatfully recieved!
