I seem to have missed this, but I put the gt cluster in my v6 car without flashing it. I bought 3 used ones off ebay, a 05, 06 and 07. The 07 has a tpms monitor in it that will give an error message, cause I don't have tpms. I just took out the old one and put in the used one. Each had different mileage. I know one other person who did this and they did have trouble with the mph being off. Mine has been in for about 9 months and no issues. I did have to buy the switches for the dash, my car already had the wiring. The cluster is just a message center,(except for mileage, which is stored on both)all the info sent to it is from the computer. So if your car is going 70 mph at 2300mph, the cluster will read that way, no matter which cluster you have.
