How's it going guys? I want to start by saying that I'm happy to have found this forum, and that I look foward to your imput and advice. I'm from Albuquerque, New Mexico. I curently own a 07 Silverado (NNBS) with the 5.3. Its the Z71, with 3.73's and so forth! The mods so far are as follows: AirAid CAI, TB spacer, Flowmaster exhaust (super 44). I got rid of the screen on the MAFS, and I recently got rid of the Diablosport tuner, i wasnt happy with it. Im looking at getting a custom tune for it. I'm looking at getting faster, making more power just like the rest of us. I would love to cam it, put a set of headers and do something with that tranny. I'd like to know what kind of luck you guys have had with these trucks and how much power you guys have made. mean while ill keep looking around the forum and making myself at home, if you dont mind!!! thanks again guys!!
