Hi Rileymax,
Thank you for your enquiry:
"Had a look at the mace recalibrated ECM tune, only thing is I can't really justify 10rwkw for $440, its cheaper than a dyno but for 10rwkw I can't really justify it. I have a full exhaust, pacemaker headers, hi flow cats, 2.25 xforce catback as well as a mace CAI and soon a manifold insulator, reckon I'll see more than just 10rwkw?"
Power output will differ between each motor so it's hard to put an exact figure on it, but you'll be happy with the upgrade. In saying this though it totally depends on the current condition of your engine and the mods you have. If you're planning to do further mods then we would recommend to hold off and have the dyno tune once all the mods are installed.
