Does anyone have the Hypertech Speedo Calibration tool in the DFW area that I can borrow or pay a few bucks to use? Need to update my 350 DRW CPU from the factory 30" to 33.5" .

 

I'm not sure the Hypertech tool will allow you to calibrate your speedometer and then just unplug it. I have the Hypertech Speedo Calibration tool for my truck, and it required me to program it on my PC, then install the whole thing behind the instrument cluster. Unless Hypertech came out with a new device, the one I have is the only one I know of.

Sorry for the bad news.

 

Thanks Rugby. I thought it was a one time use thing. Guess I will be sucking up the $250.
