    Mach 1 mods help

    Is there a big difference between the 65mm and the 62mm throttle bodies. Also I was wondering if I should look at getting the 90mm Maf or would that be pointless. I’m just trying to maximize the most out of the dyno tune. So far I have gotten the 410 gears. I’m ordering the long tube headers...

    Mach 1 mods help

    Honestly I don’t know. I bought it because the guy thought the engine was blown. I got it last year. I got the engine fixed, the plug just blew out of the cylinder. I put a short throw shifter on it and a jtl cold air Intake. was told it had 373 gears but it doesn’t. It does have an x pipe. I...

    I finally got the car into the body shop an it’s getting painted. After I’m dropping it off at a performance shop to get long tube headers, h pipe, 410 gears and a tune. Just wondering is there any other bolt on mods I should buy and put on for when I have the car tuned.

    Could use more help on my Mach 1

    Yup, still all good. The car is running great right now. Seems when I let it sit for a few days then drive it, is when it acts funny.

    Could use some help on 03 Mach 1 please

    Ok thanks a bunch. Now this might be a silly question but do I just pull that bitch out, how bad will it **** up my car if it does have a tune. Car really doesn’t have many mods, just like the xpipe no cats, and 373 gears (well I was told 373 gears)

    Where do I look to see if it’s an actual chip. Is it hard to get to and is it hard to remove if there is one.

    Sucks that the x pipe on the car now wouldn’t work. I was told it has the bama chip. If it does is there any way I can access it and see what’s tuned.

    Could use some help on 03 Mach 1 please

    Thanks. Odd question since the Mach 1 has digital odometer and a ecu would replacing either change the mileage. My wife bought me the car but I wanted one to give to my daughter later in life. Just right now I want it and want it to be fast lol. If I bought like a sct scanner would that add...

    Could use some help on 03 Mach 1 please

    Did I mention it was my family’s shop, I was suppose to get parts at his cost and a discount on labor. I want to rebuild my engine, but I think it’s better for me to get another block put it on an engine stand and build it over time. That way my car isn’t out of commission. Would a 03 04 cobra...
