Started gathering parts a couple months ago and was finally able to take my vacation to install...I started today.
Before:
5.3L: bone stock with drop in K&N and BB Tune
Transmission: Vette Servo, Yank TT3000, and stock cooler
Exhaust: Thorley Tri-ys, 22" Magnaflow, Dynomax bullet, ORY...
I figured I would take this time to introduce myself I am a new guy to the forum from OKC. Have a 2003 GMC stock, slow, and want to make it faster. Thinking of Hypertech programmer. What do you all recommend?
Thanks,
New Guy
