Hey, my name is Chris I have a 2009 Tahoe 2LT with a 5.3 Haven’t really done anything to it other than fix some of the usual problems that all of these model year have. Fought with GM to replace and warranty the fuel pump flow control module after it went bad. Somewhat think I fixed the whole service stabilitrack weird lock cycling craziness with adding another larger ground in the engine bay, also replaced the brake/cruise control switch. With all that said haha, hello! Next on my list is to hopefully do exhaust and headers. I had a 13’ Silverado Ltz that I loved with a corsa sport cat back but we had some kids and thought it would be better to have a Tahoe.
