Yes, both Asur and myself are running the Bully Dog GT for Hemi Plus.
The website claims around 30+ HP and 35+ foot pounds on the performance tune I believe. So far I've only run the regular tune so I haven't noticed those kind of numbers. But there definitely is added power and torque. Plus the shift points are 10 times better! That's the biggest difference. It keeps the truck in the power longer and when it should be rather than changing to the next gear and having to low of an RPM and then having to downshift again.
As far as fuel economy goes I was seeing 17.5-18.5 MPG tank averages with the stock wheels and tires. (Also had a CAI and exhaust). My highway mileage was up around 22 or 23 MPG so I definitely can't complain about that. So far with 35" Toyo MT's I'm averaging around 15.5-16.1 MPG and my highway mileage is around 17-18 MPG

But if you are going to use it and personalize your own tunes or buy tunes from venders that produce specialized tunes like Hemi fever and white lightning and I think a few others, then wait for the Diablo, it can accommodate many more features.
Again, exactly what Asur said ^^^
