Just getting a little ancy with spring coming up. I could use the gas mileage and of course the performance wouldn't hurt either :D . Also, I have a lease, so I want to make sure this won't mess anything up as far as that goes.

Yep, we can do them. give us a call and we can get you squared away. Alternatively you can order a PCM for a 5.3L or 6.0SS 2007 Trailblazer off our website. we can tell its a Denali by the vin.

Does the TB 5.3 tune support DOD? Checked out the website, but it didn't say from what I read. Also, what are the approximate (I know it varies from truck to truck) gains from it. I only saw the dyno from a TBSS so I know the Denali would be different.

TIA
