What Computer System To Buy To Change Speedo For 22'' Rims

[stephenson121588]

Hello guys, I have boss 22' on my truck and I want to fix my speedo for the different tire size, 1 to keep from speeding ,2 to check what kinda of mpgs its getting with the wheels on vs the stock ones. I called a few local gm shops and they told me they did not have the right computer system to change the factory settings on the truck, Finally found a shop that would do it but wanted $200! any help? thanks

Well most handheld computers are 250-500 bucks. However the one advantage to having a handheld is that you can change the tire size anytime you want, so if you change your mind down the road you dont have to pay another 200 bucks to change the tire size again.

you can have blackbear peformance do it, you just swap computers, 55 bucks and deposit, then when you send it back you get the core price back

Why go through all that just buy the autocal and have blackbear send you your tune files.

Or you could get tires that are the same overall diameter as the stocks. That's what I did when I had 22s.
