  1. You are exactly right Adam. GM has recently issued a notice to dealers that all incoming 2021 vehicles with the 6.2 engine have to have all of the lifters replaced BEFORE they can be sold to a customer. in my option GM should offer us owners of these vehicles a lifetime warranty for any lifter failure. I only have a little over 3k miles on my truck and it’s one year old now.. (I have 5 vehicles and live between NJ and FL.). So i may be out of warranty long before I hit enough miles to cause a failure. I love my new Denali but this is Bull*&$t.
  2. Wow, can’t wait to see that bad boy when it’s completed. Good luck.
  3. Yeah they seem really tough to get. I was.planning on putting a Whipple on mine but I might wait awhile and see if the ECM becomes more available. Thanks.
  4. Agreed. I’m aware that you can’t reprogram these new trucks and that GM holds the key. But my original question was why does the GM CAI require reprogramming and the aFe unit does not?
  5. I wouldn’t have minded going back to the dealer if I went with the GM unit. I was just wondering why the aFe product didn’t require an adjustment. And I guess I still don’t understand why???
  6. So I installed the aFe Momentum GT Pro Dry S Air Intake on my 2021 6.2 with the S type Borla exhaust. I liked the looks, design, cost, and “advertised” performance gains of the AFE system over the GM unit. After reading that the GM CAI requires a trip back to the dealer for a reflash to reset the check engine light, I called AFE to see if this was required on their unit. They told me it was not required. I’ve put 500 miles on the truck and it runs and sounds great. Can anyone explain why the GM CAI requires a trip back to the dealer but the aFe one doesn’t
  7. Have you heard of any warranty issues using these? That was also a concern I had.
  8. I know this has probably been discussed here before but I’m new to owning a 2021 6.2 liter Denali and was looking for some advice on installing an oil catch can. I’ve read that you really don’t need it on the new engines as they have baffles in the valve covers. Any one have experience on this with the new motors?

  10. Wow that’s awesome. Good luck. I hope you let us know if your satisfied and how it works out.
  11. Which Edelbrock are you going with? They have some bad-ass engines in the 650-700 HP range with EFI. Just curious.
