2016 sierra denali 5.3l 2wd
Hi is there a way to tune the car even though it has already been tuned by someone else
Re: 2016 sierra denali 5.3l 2wd
you'd want to have the factory stock GM programming on the vehicle before using a diablo tool on it..
have the other person put the factory stock GM tune back on the truck's ECM/TCM modules.. . or have your dealer flash them to the latest GM factory tunes...
