203Mach1ne

2003 Mach 1 with following mods:
SLP LM1 Catback exhaust / BBK X-pipe / BBK LT Headers / JLT Ram Air Intake / PHP Intake Spacer

Basically, the pretty basic mustang mods...exhaust and intake
Will these make me run rich/lean or require the need for a dyno tune, or can I go without one?

my buddy ben has the same exact mods as you except for the LTH. He runs 12.5's with no tune.

UR computer should do that for you ma man unless something is wrong. . .

OK phew...I didn't really want to spend another $700 on a good tune, especially if I don't need one. I know it won't hurt, but I'd rather put that money towards some new tires

You dont NEED one, but a tune will make it run better.. even though you dont really need one you may want to get it dyno'ed to make sure its not rich... if its rich you're leaving power on the table...

I dont know about where you are, but most tuners will tune it w/tuner (sct or diablo) included for around 500.. but no, it's not necessary.

Yep, it is expensive but you will be happy when you get one. If you plan on doin anymore mods anytime soon you might as well wait anyway. I would say (cash permitting) just wait until you think your done modding for awhile then get a tune. Usually they can squeeze a substantial bit of HP even with minimal mods.

yeah I only plan on doing those mods I mentioned (Full exhaust and Intake)
I guess I might get a tune, we'll see once everything is on
