The Bacon Hauler (‘12 Cop Charger)
When was the tune done (with respects to the other mods)?I guess the only way to know for sure is to go back when cooler temps prevail. I would have thought the tune itself would have added a little bit.
More importantly than the numbers though - how does the car feel/drive? Ultimately that’s all that matters. I’ve heard the reduced torque management done with the tunes makes the car more fun to drive even if it doesn’t affect peak HP.
The tune has to be done after the other mods are installed, otherwise the other mods would work against anything the tune did to improve perfornance.
Beyond that, it is perfectly reasonable to expect a heat-soaked engine to be 10-15 HP/TQ down from where it would be if not heat-soaked. Was yours heat-soaked at the time of the dyno run? IDK, I’d need to see the other data from the run to be able to make that call.
But if there was knock detected during the run, the PCM will have pulled enough spark timing to mitigate it, and every degree of spark timing lost, however temporary it might be, equals less HP/TQ making it to the rear wheels.
