2020 jeep gladiator procharger kit
I have a 2020 jeep gladiator, it was initially flashed with diablo that came with the kit. Long story short the tune was wiped and I no longer have the diablo tuner. I have been working on the tune with HPTuners but I keep getting error U1428 inaccurate engine torque received and it goes into limp mode. also c121c torque request signal denied, DASM pcm disable ecu and ABS disabled ECU. Any Ideas?
