Hey guys, Just a quick question, has anybody done the Blackbear tune to there 08 and up GM 6.0? Just wondering if you have post results if you can please. I am looking at the hand held custom tune ...
I highly doubt you'll see 30HP or 40-50TQ! More like 20/30. Gas mileage may only be 1 mpg better at most. However the way the tuner changes the shifting strategy of the trans is way better than what the factory ever did. You should be able to run whatever octane you tell them you want the tune for. On my X I have 3 tunes, all 89 octane. I could've had 3 different octane levels if I wanted,but thought one tank of fuel for all 3 is good!
