The MPH seems low though for the times that you're running. Any ideas on that, or are GLS's just aero challenged at the top end?

11.20s is definitely moving for just a JB4 and some fuel. I'd like to think that as the temps cool off and you get the chance to dial the truck in, that 10s are possible with just the JB4 and a good map 6.

True, I didn't even think about the wheels. Still. One amazing truck. If anyone can get an SUV in the 10s with just a JB4 and some octane, it's you. I'm rooting for you as the temps get colder. Even if you had to increase fuel delivery, I consider that fair game and still "Just a tune".

Just for giggles I decided to use this http://wallaceracing.com/hpcalculatorquarter.php to calculate horsepower/gains.
Using the averages of all the runs (excluding the 116mph run, since I lifted before the finish line) and using weight of 4,775lb
