I'm using a mach1 guage set in my 04 gt but I had to use my programmer to change my gears to 3.55 for the speedo to work even though I only have 3.27 gears.

so would i need a programmer to calibrate my speedometer?

 

[Tazzy]

Yes, either a programmer or a speedometer correction calibrator.

my autometer lunar cluster is off as well. the MPH is WAY off (may be due to the 28" tires) and the rpm is off by 200 rpm too
