Who's the tuner?
No, it's not that, the O2 simulators are for the rear O2s which don't affect any tuning. They exist only to ensure the cats are working properly for emissions.Maybe due to the fake O2 sensors?
Sean from Hemifever. He has been patient and a great source of info throughout this process. Per his request, on Monday, I will be getting on the dyno and will record the AFR using their wideband. I’m hoping that I can get the right info to get the tune fixed.
If you go with HP Tuners, I strongly recommend Curt Dusterhoff.My backup plan, if this doesn’t work out, is to convert over to HPTUNERS. There is at least 1 tuner local to me that prefers to use them.
Curt tuned my Hellcat, made 892whp. Never had any issues.Thank you, I’ll keep that in mind.
