Another one fixed up so the owner can finally enjoy it!
This Challenger RT arrived with a very poor tune that prevented the owner from being able to drive or race the car without issues. The transmission tune had also damaged the transmission and it would not complete a 3-4 WOT shift. We tried to tune around the transmission issue but in the end the trans simply needed to be replaced. The fuel system was also not up to the task and pressure was dropping at high RPM.
We pulled the car off the dyno, waited for a slot in the schedule, and got to work. The trans was rebuilt and upgraded by SOUTHERN HOTROD, LLC, our high stall converter from Perfect Converter installed, as well as a FORE fuel system. We then dropped the pulley size to a 3.25 and added E85 to the tank.
Not only did the car gain 135whp and have the fuel system and transmission to handle it, but it can be started, driven, raced, and enjoyed. Looking forward to dialing this one in at the track!
