first of all i know next to nothing of LPG other than it runs cheaper and nowdays there are systems that don't lose too much performance.

can someone recommend me a system to use as I don't know which one and there are so many of them. What I want is reliability and not too much loss in performance.

also, is ther anywhere in Sydney which does a good job. I called a few places but they all have the feel of drive in, let us take your money, drive out and you have problems with the car but we don't want to know about you anymore.. I remember ringing up a place a while back and the bloke really knew what he was talking about. Castle hill I think it was but a google of castle hill lpg revealed nothing. I think it was an impco system ot something.

Also, I have an exhaust, extractors, air intake, and a camtech cam....... will this have any effect on the LPG system's operation?

Thanks.
