    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 tune on my 17 High Country 6.2L and see some difference. Trans fluid was changed with Amsoil ATF as soon as it left the lot when bought new with a relearn .Never had a vibrations like you see on many forums. Did have the clunking/ lurching but the relearn and tune nearly took that away. Have a Launch X431 Pro that i can do transmission relearns when i want. My experience with Trifecta is good and im enjoying the tune.

    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?
  5. High Country 6.2L/8
    Aside from the vast opinions on to have or not. Did anyone install one of the B&M trans sticks on there 8 speed? Have one but didn't install yet

    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?

    Has anyone installed B&M transmission dipstick?

    Known or Fluid Film is a popular choice yes. As for what's under mine only the dealer knows lol

    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

    No it's a pleasure vehicle no towing etc.... thanks

    How long ever 3 years regardless of kms?
  12. High Country 6.2L/8
    Would it be overkill to drain coolant/ flush on my 17 at 36,000kms and when would it be a good time? 5/ 150,000 kms seems like way too long.
  13. High Country 6.2L/8
    Dealer done mine the undercoating before it left lot, seems to holding up 3 years and rust free and I live in Nova Scotia a true test.
