what about this. i found a company that sells a device that goes in to the wire that on the back of the tail shaft. the trany gear reader thing( dont know real name) but they say if i use this device it will fix the 200 problem
so basicly i put this in, then calibarte it to my system. does this make sence

come on, someone must have a concrete answer. I think the money that Granatelli charges to recalibrate is rediculous. Seems like they could be a bit fairer on thier prices, esp. since it probably takes them hardly anytime at all to do it.

they used to(past) charge 300. but they dont do it any more.
i am buy a v-6 speedo. and just bought anouther v-8 speedo and going to open them up and see the difference. cause i know if you take a v-6 and put it into a v-8 car it reads right. and vise verise. v-8 cluster into v-6

To those thinking it is in the ECM, you are absolutely wrong. Quit spreading BS and misinformation. As some have already said, it is in the gauge cluster itself. You can change tire size and differential gear ratio in the ECM, but you can not alter the speedo range (ie: from 120, 150, 200), as the ECM does not control the speedometer, it does calculate the speed of the vehicle for trans functions and CAGS, but it does not send out an MPH signal. So, stop spreading "my buddy's friend's cousin's sister's boyfriend change his with the ECM" bullshit. 
The gauge cluster receives pulses from the VSS and converts it to a signal the Speedo can use to display a MPH.
The gauge cluster receives pulses from the VSS and converts it to a signal the Speedo can use to display a MPH.If you had a 3.42 gear and programmed the PCM for a 4.56 gear, it would look correct on the speedo, but you odometer would be off by 33% as well. The speedo would think you were going 150 and in fact you would be doing 200 mph.
The only way I would do it is like Granatelli did, the right way by reprogramming the cluster.

I know mustang guys that have changed the gears inside the clusters for the needles. Thus a GT cluster to a Cobra R cluster. Only difference was 2 gears in the cluster. Thats mustangs though...

I wonder if no one replied with an answer for the same reason I didn't at first.
7 years ago I toyed with the idea of installing a ZO6 gauge cluster and, through VERY minimal research, found a FEW places in Fort Lauderdale that specifically recalibrates speedometers.
I didn't have to use that route since I chose to purchase the Granatellis but IIRC the fee was $70-90.
Just do a local search in your respective cities. It's not rocket-science to reprogram a speedo.
