Very nice! What field of engineering are you in?

On a side note...I have noticed no substantial gains in mileage with any of my performance mods. CAI, cat-back, or Hypertech Max Energy tuner (on either the standard tune or max performance tune). The truck is more enjoyable to drive and performs better, but I don't see any improvement at the pump. Eventually I'll do the BB tune, though, and hopefully see some MPG gains there.

My overall average since July 1, 2008 (18,709 miles) is 15.1 MPG. The highest I've ever averaged (minimum half tank of fuel) is 19.9 MPG. The lowest I've averaged (again, minimum of half tank of fuel) is 11.8 MPG.

I was getting around 7 on my 03 tahoe due to what i think was an intake gasket. On a half a tank a gas i got 101 miles. Now that is terrible gas mileage on a stock vehicle. Once my hoe is fixed i am definitely going to get a BBear tune i hear to many good things not to invest the money in that.

Sorry, just now saw your post. I have a Chemical Engr degree and I work in the natural gas industry here in the Barnett Shale.

My overall average was 15.35 before the tune, with the highest ever at 16.68. It has now increased to 15.68 overall in just a few tanks, and the average I have since the tune is 16.4.

I still want to collect more data before I determine payout.
