Did download without any additional changes yet. Performance has increased. Also sounds better. Very easy to do.

This is how Chrysler should have had my car programmed at the factory. I have a Borla performance exhaust system and am using the factory CAI (cold air intake) with the stock paper air filter. The Diablo setup I'm using is their 91-Octane factory tune, with raised shift points (6000 rpm as opposed to the stock 5800 rpm), increased shift firmness, and autostick auto upshift mode 1. My fuel economy has increased, which more than offsets the slight extra cost of having to use premium gas.
