Talk to joe or go to Trick Tuners, SCT Flash Tuners, SCT Flash Custom Tuning, PLX Devices widebands and gauges, SCT Flash tuners, SCT Xcal2, sct livewire, sct xcalibrator and read there is tons of tuning info on there and joe is a A++ guy to work with! But if you are going with stock heads and a home P&P Job you should be fine if you dont get to extensive with it. but you WILL always get more power and economy with a good tune! __________________ 2002 mustang gt 5speed, procharged...Fun PRO-M Blowthru Maf for 42lb with iat sensor! must go trade for LMAF!! 1999-2004 supercharger kit for sale. plus extras! check out my garage for details

you can run it with out a tune no problem, just reset your computer and it will make small adjustments for the improvements... computers are smart, they can change small things like fuel and spark and shit to help it run to "Factory Specs" ... which is a complete and safe set up

to make the best of your improvements you should tune the car

Get a tune and do it right the first time. if you need to save the money i would buy the heads, bolts(ARP) and gaskets (fel-pro or =) and let them sit untell you can get a tune, or bring it to the dyno. IMO Think if you lose a few mpg how fast it could/would add up on a DD and you could have just bought a tunner and a tune and be in the same cost with more power idk about you but thats what makes my world go around! __________________ 2002 mustang gt 5speed, procharged...Fun PRO-M Blowthru Maf for 42lb with iat sensor! must go trade for LMAF!! 1999-2004 supercharger kit for sale. plus extras! check out my garage for details

do you even know wut youre talking about? porting your heads doesnt change the compression ratio of the engine. you wont throw codes and you wont lose mpg, if anything youd gain from having a more efficient engine
