currently have hks bov, and 3inch straight pipe exhaust any gains from the exhaust what other things can i do to it before i need to start getting difference parts and a tune im also finding it hard to find someone to tune it here in edmonton alberta canada

 

Search. You will find plenty of info on all of this with a simple search. Realistically anytime you change anything with exhaust and air intake you should get a tune. UICP and LICP and a bigger IC is something to look into. If you want substantial increase for the best money buy yourself a set of cams.
