quick question: you mentioned doing the adjustment
"in the driveway"....i've recently been told to check my turbo's effectiveness using a boost guage at the plenum fitting going to the ALDA...but been advised: check it under LOAD,say climbing a hill above 2500 rpm...vs 2500 running in Park....as I understand the physics involved...spooling at 2500 rpm in Park will require much less fuel burn...said extra fuel burn under hill driving LOAD being different...right?...extra fuel burn = more exhaust gas temp/expansion = faster turbine spin velocity on hot section=more psi cold side boost to the boost guage?....ergo, would a setting dialed in park in the driveway read something very different under load going up the hill?...& most importantly
WHICH is the correct MAX you want to keep from damaging the engine, while preserving your right to make TORQUE & blowing by the factory engines going down the highway....??
