Finally hooked up the laptop just to check it out and change up the tranny a bit. I won't be tuning the engine 'til I swap out for the LS6 that's on the stand. I changed up the shift pressure, time, and mph of all gears in about 15 minutes and wrote it to the truck. Went for a spin and it works perfectly.

Anyone tells you these things are complicated and you shouldn't fool with it, don't believe 'em.

Hey, can I use this as a DTC scan tool on my suburban or any other car without burning any credits? thx
