PSOM Programming
Hello
I was wondering if anyone could tell me how to change the psom setting on my trucks instrument cluster to correct the speedometer being off now that I put 35 inch tires on my truck. I was also wondering if there is any way to figure out what the correct code would be to put in it? The truck is a 1995 f150 302 automatic 4x4 8.8 rear end iam not sure of the gearing. I have swapped a 1995 lightning cluster into my truck with the 120 mph speedo, but installed my psom on the back of that speedo gauge. Iam off around 8 to 10 mph right now. Any help would be greatly appreciated
Thanks
