I had a 2020 5.3 1500 GMC in Dec 2020. I drove a 6.2 while my 5.3 was in service. THAT DID IT !! I traded for a 6.2 Denali that day.6 .2 badass power and the 5.3 was weaker.
I have the RANGER plug in for the 5.3 and it works perfectly on the 5.3, BUT, the 6.2 does not recognize the codes. I will sell the 5.3 RANGER for $125 plus postage. If interested contact
[email protected]. I would like to know if anyone has a tune for the 2020 6.2.
I had a 2010 6.2 camaro but that tune wont work on the Denali.
