RE: WOW...what a MPG improvement!!!!
Linus..... I asked teh dealer about that because I still have my stock rims/tires sitting in my shed. He said that if I wanted to put them on and bring it in with a full tank of gas that they would drive it for 1/2 a tank and refill to see where the mpg are at, but.... depending on how busy it is it could take anywhere from a week to 2 weeks. This was the same answer from all three dealerships within 50 miles of me. I'm not at the point yet where I am that concerned overr it to let them have my truck for 2 weeks so a tech can do god knows what with it while he burns 1/2 tank of gas. I have a call into gm though about it...my gripe is the dealerships won't even run the pcm through a programmer to see what the settings are...damn I know it can be done, we did it all the time when I was a gm tech. Hopefully the regional service manager can get at least taht done for me.

That sounds like you would wind up getting the used end of the stick on that. I envision mechanics and parts people running all over town picking up parts from vendors, and taxiing people around, at your expense. It would seem to me that they could plug a scan tool into it and drive it around the block while monitoring fuel flow
