I just got off the phone with a shop that I wanted to install 4.10 gears on my 04 GT. I was quoted 275.00 for labor, and another 500 for a chip to re-cal my speedo after the gears were installed. My question is would it be worth it to just get a handheld tuner such as a diablo or SCT and just get the gears installed and then re-cal the speedo myself? Correct me if I am wrong but can't you do more tuning that just a speedo re-cal with the handheld tuners? And aren't they under 500.00? so wouldn't this be the best bet?
