2022 Dodge Charger S**t Pack | HDP 550
This one came in for our HDP 550 package featuring our in-house PCM unlock, Stainless Works long tube headers, high-flow catted mid-pipes, cold air intake, and a custom street & dyno calibration.
✅ 477.5 WHP
🔥 496.8 WTQ
Swipe over to check out the dyno graph. Peak numbers are great, but the biggest improvement is the torque. The long tube headers really wake these cars up down low and through the mid-range, and with the custom calibration we were able to clean up the power curve and get the most out of the factory SRV system.
A straightforward setup that completely transforms the driving experience!
