setting the speed without a tuner

  • Sponsors (?)


well, it allows for your set up to grow. If you go to an o/r midpipe it will keep the SES light from coming on. Plus you could pick up a good bit of power just from adjusted timing, but you will have to run premium fuel.

i have an 01 gt and i'm swapping the stock gears for 3.73's. is there any other way to recalibrate my speed without buying a tuner?

I'm tempted to say just cruise alongside a buddy who's driving at X mph, then pull your needle and reset it.. but I think because of the ratios involved it would still never be quite right without a tune or a speed-cal.
