Dumb question.... Mileage booster.

[dm05z71]

Ive got a dumb question. On the trinity's homepage on this site and a couple other places I keep seeing this mileage booster. My question is, Is it just automatically integrated with the tunes or do I have to access it somewhere. I drive a 2005 silverado 5.3 and when I tuned the vehicle the only options were Diablo tune (91-93 octane I found out), 87 octane, Factory HP, and Original backup.

that tune is not available for your 2005 truck....

2007 and newer vehicles with the AFM/DOD system only...

Is this the case for all of the 07 and under vehicles? I have a 04 cts v and i do not have economy mode or any of the other modes. Just the diablosport performance tune

Its only on vehicles that have Displacement on the demand (AFM). Since that debuted in 2007, nothing older then that will have it.

plus, it's an 87 octane tune anyway.. you don't wanna be running 87 octane in that cts-v, heh...
