    Where do I get 03 GT Quarter Window Scoops?

    I have tried to search for those scoops for the quarter windows and have not had much luck. Does anyone know? There used to be a site that had a selection of them but I can't remember who. 05 stuff is taking over!

    How long before gas goes bad?

    Typically our wonderful pump gas starts going bad in 28 days.. Use it up. You can get 2-3 months if you use a bit of Stabil gas treatment. (red stuff in metering jug at local parts store)

    Need help. Loaded New SCT SF 91 oct tune on 03 GT

    Using the new SCT SF Tuner, I loaded the 91 oct tune to my 03 GT using 92 octane gas. The car runs great with the exception of some pinging when I goose the throttle at at a stop (neutral). It happens at the beginning of the rev. What can I adjust to get rid of this? The mods on the engine...

    Do I really need a tuner with these mods?

    Thanks, I think I will look at the Newest SCT. Sounds like it might be a handy investment. A dyno tune might be a good bet too.

    Got your Horse Power.. Fuel Injector Formula

    The brake spacific is close enough to give these guys and gals a precise estimate of the fuel injectors needed. .04 to .06 is used for stock to SC engines anyway.

    Do I really need a tuner with these mods?

    From what I hear my 03 has 24's. Is this right? I know if I use bigger injectors I will need a tuner for sure.

    Got your Horse Power.. Fuel Injector Formula

    Fuel injector size Formula: Eng HP x BSFC ______________ = Inj. lb/hour No. of Inj. x 0.8 BSFC=0.4-0.6 (0.55 is used) Have a nice day!

    Do I really need a tuner with these mods?

    When you use this formula for Injectors, mine are about at the end of there rope. You guys might want this? That is why I am changing them out. Fuel injector size Formula: Eng HP x BSFC ______________ = Inj. lb/hour No. of Inj. x 0.8 BSFC=0.4-0.6 (0.55 is used)

    Do I really need a tuner with these mods?

    Well, I was going to put the 5/8s fuel rails and 30# injectors, and possibly the The new alluminum intake that Performance Products just came out with. Otherwise I would like to get as much power out of my 03 GT as possible W/O No2 or SC.

    Do I really need a tuner with these mods?

    I have an 03 Mustang GT. It has a 75mm T/B & Plenum, Ford Racing Cold Air Intake, Ford Racing Ceramic Headers, and Flowmasters on my floor in boxes. Do I really need a tune when installed? I was thinking about a SCT if I need one. What if I dont tune? What kind of gains either way? Thank...
