I'm looking for just a module that will correct the speedometer from tire and gear change. I don't want to buy a programer because I'm waiting for Banks BossHoss bundle. Any out there?:(

You can purchase something called tru-speed from superlift. I had one on my 03 8.1 with allison. On my 05 Duramax I got the Diablo Predator to fix speedometer because it also has diagnostic capabilities and can erase codes.
