I have a friend that has a 08 GMC sierra and he want to see or hear of everyones truck. He wants to do something to his truck and doesnt want know what to do but a tune and i have been telling him to get some long tube headers are a start. Then get a tune on the truck but he seems to push it to another day. So i can prove him wrong about everyones truck can be motified to the extent.

 

These are some videos of my tuned only 5.3 L CCSB ( Note: The Speedo is in KMS not Miles)

no cam no videos

 

I have a 08 sierra no vids or anything... but I have little things done. I ran stock 16.4 in the 1/4 mile. With just a tune, cai and muffler swap I ran a 15.6. Next on my list is a 3000 stall, vette servos, and long tubes as soon as pacesetter makes them for the 4wd trucks. After that I am goin with a cam. I am hoping to go from a 15.6 to a 14.5 with those mods. I have looked at prices on that stuff if you are wondering but I would do at least the tune, cai, longtubes, cat-back or muffler swap, stall, and servos. It will make it like night and day.
