You don't sound like a twat; you sound English to me.

One of the advantages of modern electronic engine controls is that they eliminate a lot of the minor tuning and tweaking necessary in the old days.
First, make sure all the normal maintence items are looked after, such as plugs and plug wires, valve adjustment, if applicable, new oxygen sensor, if arequired, etc.
The intake and exhaust mods are the easiest to do, as is a performance chip for the ECM, if they are available for your car.

thanks i apreciate the reply but i dont know what an "ECM" is but i know how to do all the tuning to the air and exhaust systems....

any other ideas....

ECM = Engine Control Module
