chips anyone?

03stangGT · 07-28-2003, 01:56 PM

I have an 03 gt, and I'm going to be putting 3.73's in it, I was told I need to buy a chip to fix the speedo, and milage once the gears are in... I have no idea what anyone is using, its a daily driver, I go to the track every so often. Any ideas or suggestions would be helpful.....

If you had an automatic it would be more worth it to pay the price to get a chip as the computer controls the tranny. I have a 5-speed and got the SpeedCal as well.

the speedcal sounds like a good idea, on the site it says 99-01, I've got an 03. Secondly I plan on buying a chip anyways, soo I was just wondering what everyone suggests, what works, what doesnt etc... thanks for the ideas...

If you go with a chip i don't think they come pre programmed for that,i have a diablo chip and i still use a speed calibrator.They would probably have to program that specially for your car.

The Speedcal should work with your '03. But if you already planned on getting a chip then you might as well just get it programmed for the gears and bump your timing to 14 degrees while you're at it.

yea I was thinking about getting a steeda timing adjuster, and bumping up the timeing about 15 degrees, I heard it helps a lottt. I am going to go with the speedcal though. thanks for the ideas

I'm not sure if the '03 models are any different, but i bought a superchips power programmer for mine. This allowed me to recalibrate my speedometer, change the computer programming, adjust thermostat controls, speed-limiter, etc. The speed calibrater was going to run $150, i picked the programmer up on Ebay for $225.
