Is it a waste of money to upgrade to performance coil packs and wires? Have a 2017 Silverado with 6.2L. Heard some negative reviews about throwing misfire codes. I'm sitting on the fench because of the $1000 my wallet will be lighter as well. Sure they look great but want more than looks
I installed the Trifecta tune on my 17 6.2L/8 speed and have no issues works as advertised and customer service was great. Not sure why there are some negative comments but to each his own. Would definitely recommend as GM will never fix the issue
Trifecta has a tune that is around $700 for 6.2L. Does anyone have any information on this other than tech from the company that says significant gains?
Your not the only one that has this issue, I'm on my second set and ready for the third and theres only 35,000kms. I'm not hard on brakes but it seems GM cheaped out again. I could get another set under warranty but why bother if they only last for 10,000kms. Anyone have any suggestions on a good rotor that will last?
My 17 High Country is rust free and 3 years old, lots of undercoating applied yearly by the dealer as part of the sale. We live in Nova Scotia where any vehicle is bathed in salt
I put Amsoil ATF in my 17 High Country 6.2L last year because of slight vibration/ shudder long before this so called Mobil fix for the issue. Guess what no more issues after Amsoil went in.
