I used my new 2815 for the first time this weekend. I have a 2006 Trailblazer SS (6.0) It asked me for the tire height, I went online to Tire Racks site and found my tires P255 50 R20 Goodyears. It said 30.1. I programed that in, It seems like my speedo is fast,(may just be me) but does that size seem right. Would it make much differents in the speed if I put in the wrong tire height?
Thanks for you help, Love the tuner so far, truck runs like a bull with dyamite up its A**.

Thnaks Ron I will remesure them and then reset the program. Do you have any spec for programing the TBSS 6.0 that I can try? Dont really want to do to much without knowing the limits of my veh that might harm it. It is stock.
