thnx for the info, iv since had a heavy duty clutch put into the car since the stock one on the car was completely stuffed and running basic capa 10psi tune, and I have been looking for exhaust systems and somewhere to get a dyno tune on my car but the amount of money im bieng quoted differs so much from performance shop to shop! bout a grand diff in some cases. I have the injecters fuel pump and valve springs ready to go and looking at the exhaust but unfortunately because im not knowing what to expect from upgrades in thse departments but 250rwkw does sound good but 300+ sounds better from what I have been reading in the forums, I dont mean to be rude but what sort of price will I be looking at for a dyno tune once I have had these extras installed I have been quoted $600 ish to $1800 depending on place in perth and most were quite rude and didnt realy care for my business any1 from perth able to help out with the right place to go for Dyno tune, dnt mind going for a drive to get the dyno so basicly anywhere in perth that's good for a dyno is good for me :D
