I had my 12 all redone, I have a kenwood deck and kicker speakers and tweeters with a 10in kicker truck box sub. I have a 600w 4 channel amp running the speakers and tweeters with a 500w amp for the sub.
I just hit 113k on my 2012 and it seems like I have a lifter tick maybe? Should I try an engine flush or maybe run ATF in it at an idle for 20 mins or so and change the oil. Just looking for some feed back. Thank you!
So there’s a guy on Facebook selling it for 200 bucks , if I did buy it what would I have to do? Aren’t these vin locked? He said he holds up to 5 VINS
Hmm it’s definitely a great review to ready though, I’m always hesitant on tuning a GM again. I had an edge programmer in my 2009 Sierra 1500 and I blew the pumpkin apart and the spyder gears too. It was covered under warranty but I’m convinced that it was the programmer. I have a 2012 Tahoe now...
