Post subject:  Speedo Calibration

I have a 99 Z28 which I have just replaced the gears from 2.73 to 3.23.
My problem is that the speedo is now reading incorrectly and the auto box shift pattern is wrong. Now I knew this would happen so I need somebody who has got an HP tuner or Hypertech device to reprogram the PCM.

Is there anybody in the south who could help me out.
Cheers
John

hi,

i've got EFIlive tuner, but im up here in Leeds. Plus would need to get a license to tune your car, there about £75 quid. But i'm up north. Try get a price from some tuners down their, auto pontiac may do it. If not I could do it at a visit to santa pod in future but noth for month or so.

Thanks for the reply, can't believe I didn't think of Autopontiac. If I have no joy I may well be back in touch :D
