Hey Mike,

I had a DiabloSport tuner for my 2008 Hemi Charger before trading it on my 2010 Gt 5-speed. I used the 91 octane tune and it made quite a difference. What can I expect with the DiabloSport 91 tune on my GT? It has the Roush off road exhaust, but other than that it is stock. Will the difference be as noticable on my seat-of-the-pants dyno? Thanks.

Larry

 

The HEMIs really wake up like nothing else with a tune, but there are similar gains to be had on the Mustang.
You'll notice better throttle response, less TM intrusion, and more power everywhere!
