Made some solid gains over the stock trim on race gas. We added an upper and lower pulley, offroad connecting pipes, fuel system and E85 to give it a good bump.

Stock w/ MS109 on the H.O. Button: 708 whp, 700 ft/lbs
Modded on E85 on the H.O. Button: 855 whp, 905 ft/lbs
For reference, stock Hellcats tend to do around 600whp stock on the same dyno.
