04.5 Computer Upgrade
After installing my new H2 BFG 315's, I went into to the dealer and had them recalibrate the speedo. While there, I got to talking to the Mech and mentioned that I understood there was an upgrade that could be loaded into the computer (thanks to you guys). So he wrote on the invoice that I was complaining about white smoke and hard starts and the warranty covered the upgrade. Well I'm here to say THANKS boys. I noticed a 5 mile an hour increase around town on the trip computer right away. I haven't made out on the highway yet but am looking forward to that. And it does start better. With a very noticable increase in HP. And furthermore, the Hummer tires look awsome, ride awsome, and I'll even say the tranny seams to shift better. Thanks again.
