    Well, I got mine in yesterday and installed it today. The installation was a bit more of a PITA than I expected, mostly thanks to the fuel lines not being long enough when the spacer is installed. I noticed an immediate increase in power both on the bottom and top end. My Suburban now chirps it's rear tires with no problems, something it could not do at Denver's altitude before. The top end has more get up and go as well. I'll see what kind of mileage improvements I get, if any. I'm making a trip to Amarillo, TX this weekend. Last time I went, I averaged 12.xx mpg.

    Is yours a 4x4? Which headers did you go with? That'll probably be my next mod. Also, which programmer did you go with?

    i went with pace setter shorties from summit, they were the cheapest they had like 140, then i had true duals with an x pipe to some '07 stock mufflers off my step moms mustang gt, its not a programmer just a chip, its a hypertech, put it on a long time ago and it made a big difference, the spacer was 3rd to the mix, and it has helped alot too, oh and yes its 4X4, 2500 long bed reg cab with 14bolt 4:10s 33" tires
