speedometer recalibration

[philly53]

so i just got my car back not too long ago from the shop they were putting in my headders and 3.73s in and it has thrown my speedometer off by about 7mph this is on a 99 pontiac firebird. ive asked all the dealers and the best they could do was 323 or 342 at the best and cant recalibrate my computer to 373s .. just wondering if any one knows where to get something to recalibrate that

That's a lot of cash for a 7mph, I would just live with it until you have more reasons to buy HP Tuners for yourself. If you had an '02 I could do it in like 30 seconds... Don't pay somebody that much money to do it, its not worth it. Plus you can get out of one speeding ticket with it being off! Sounds golden to me!
