  1. 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
  2. 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.
  3. 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
  4. 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. Im not seeing the reviews that great, almost bit the bullet but now im glad after seeing this that i didn't flush $669 Canadian.
  6. 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
  7. 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?
  8. I thought so, one dealer told me they do and another don't, so I just wanted to be sure. I have two sets from GM that dealer gave under warranty brand new and a front set to fit 2020 that cover under the gas pedal again dealer gave but dont fit. Guess I'll be selling 3 sets of mats lol. Thank you
  9. Does GM offer a mat that covers under the throttle not Weathertech or Husky and what's the part # if so? I can't find them checked every dealer and they said they don't make them but I'm sure I seen they do on here but can't find it. 2017 High Country
  10. Have a 17 High Country 6.2L, want a nice deep tone not loud can I get that with just a muffler or do I need fatback??
  11. As for cabin filter I bought a K&N no more tossing. All truck fluids were changed to Amsoil after driven off lot but the coolant and brake fluid, which will be done at 60,000kms
  12. Known or Fluid Film is a popular choice yes. As for what's under mine only the dealer knows lol
  13. 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
  14. No it's a pleasure vehicle no towing etc.... thanks
