Well picked the Durango up last night and she is a beast. I know I said P1X but somehow got a D1😀. FInal numbers ended up at 567.9 RWHP and 471.5 TQ. Only problem that they ran into was my Diablosport T2 tuner froze and took a dump so ended up switching over to HP tuners. Other than that install was pretty straight forward they said. Ill post up some pics later today.
