new to diesel tuning i have been trying to raise the boost to 270kpa up to 3750. i have changed every boost table, torque table and even set the wastegate duty cycle to 70% for all high load 3000-4000. yet no matter what i changed requested boost and boost slowly drops off after 2700 rpm. are there tables missing from hptuners required to get the job done? also on the scanner aside from boost and rpm there is basically no useful pids to log?
thanks in advance for anyones input.
