Hey guys Ive been on this forum a bunch getting ideas and knowledge from everyone about problems and things to do to my truck. I live in Kansas, south of the Kansas City Metro area. I have a 2003 GMC Sierra 1500 5.3 Z71 sitting on a 4" Rough Country Lift Kit on 33" Nitto Terra Grapplers with 17" Helo rims. I love my truck to death and can not wait to get more done to her. Hope to gain knowledge and share mine with y'all. Been reading about tuners and 06MonteSS I will be in touch with you when I have money and decide to pull the trigger on one of those DiabLew packages.
