on a dodge is pe commanded by pressure or throttle angle?
assuming dodge pe is tripped by throttle angle:
if your running with a turbo at 50% throttle light load making 8psi, would you have it engaging PE (open loop) at that low of of throttle angle?
tripping pe mode at a low throttle angle is going to cause issues in other driving circumstances, where it can run way too rich when it is not making boost 8 psi of boost but is at 50% throttle angle
my interpetation of "part throttle boost" tuning is not the small area of the data log where you transition between cruise and wot with it.
part throttle boost tuning for me is when you are lightly cruising under low/medium loads, boost, and throttle angle which can vary the fueling needs significantly with turbos, where impellar speeds are not derived from the crankshaft, but varying pressures in the exhaust system.
