Brought the truck to Truckfest @ McCray's Farm on Sunday and took her up on the dyno. It's a Dynojet 248 operated by Brand X Performance. All that's done to the truck so far is in my signature. I originally planned on running my 100hp street tune but I caved in to peer pressure and bumped it to the 160hp tune. :cookoo[1]: Didn't do any tranny relearn or anything and the pulls were with O/D on because I don't yet have a O/D lock out. I wasn't able to run the truck myself because of liability reasons. First run she made 417hp and 693 ft-lbs torque. :gearjamin Second and third pulls weren't so great because the Allison went limp during the second pull. Still even in Limp Mode it made 387 and 386hp and over 600ft-lbs. There was virtually no smoke on any of the pulls.
