No doubt it's been asked a zillion times before, but what sort of power increase would I expect to gain by fitting an E30Zone Chip to my standard M40 powered 318i auto?
I know it does'nt sound alot at all but the chip does'nt really increased performance on these engine's, it's the throttle response. I have a 318i with a Viper 2 Extreme chip and the throttle response is great
