Hey all,
I have a 2016 Challenger Hellcat with a 4.5L Whipple. Still running stock TB at the moment as the twin 71 is backordered. I'm having an issue with it going into a limp. Pretty easy to reproduce the issue...just slowly increase revs and at 4000-ish, it will cut and limp. The throttle body lightning symbol comes on the dash and it's limited to 2000 RPM for a short period of time before it resets. No DTCs get set.
From what I can tell, the only thing that looks weird to me is that the "actual torque" exceeds the "driver demand torque" by 15-20% at this point. I'm assuming that it's cutting because it sees the engine making way more torque than expected...but that's a guess. I have no idea how to "tune" this however. if that's even my issue
What's been changed in the tune -
* Changed the S/C bypass values - lowered them a bit based on some other posts I've seen
* Adjusted the S/C airflow up a bit but that doesn't seem to help my cause any at this point
* Otherwise fairly normal tune stuff done based on old stock blower and pulley setup
Can you guys help point me in a direction??
