Hello everyone. Ive been lurking for a while and decided to join. I have a 09 sierra rcsb 4.8l w/ the 3.73's that is currently stock but i have a bunch of parts waiting for me when i get back to the states from Afghanistan. I plan to do the intake,exhaust, and programmer(until i decide on a custom tune) immediately upon my return, with a vette servo, some 22's and a 3/5 drop shortly after i get back. Thanks in advance for the info ill be asking for.

 

welcome
