Hey all, i have a 03 monaro and was just wondering what would be the best for performance and price mods to do.
So far i have done to it : pacemaker tri Y's , Hi flo cats, twin 2.5 xforce, Growler induction with bigger throttlebody (looking to replace for OTR if its worth it?) Mafless tune and made 308rwhp.
Im thinking of doing 3.9 diff gears, OTR, cam and springs and get a re-tune to 98 octane as i only got it tuned to 95 octane, but is there any other little mods to do first? and what cam and springs should i use as im not looking to put a stall converter in or boost it. Thanks heaps
