Re: Speedo and Hypertech?(not the bathing suit)
I'm pretty sure that it is the stepper motor because now it is really jumpy when accelerating. How hard is it to remove the bezel around the cluster. I have taken several mustang clusters out but I don't want to go and start pulling on the dash and it be screwed down.
Does the bezel just pull loose with those crappy plastic clips that break half the time? Thinking of trying this cluster from ebay. Anyone have a better idea. I think my warranty has a 100 or 200 dollar deductible so I will just do it myself.

Yeah, I love my hypertech also! Truck runs so much smoother to me. I was just asking if it might cause the speedo to do that. I wasn't aware there was a known issue with the cluster.

Re: Speedo and Hypertech?(not the bathing suit)
Had to have my cluster replaced on 05 model with just 9000 miles on it. I had been running hypertech most of the time and after new cluster continued to run hypertech. What ever adjustment to tire size worked as should just as it did till cluster went bad just out of the blue one day. I could tell I was going faster than speedo said I was. Dealer confirmed and changed it out. They knew I was running hypertech said very quickly it was not the programmer fault.

Thats good the dealer didn't give you a hard time. Has anyone changed a cluster out on their own?
