So I pulled the turbo, cleaned the vnt again and set the actuator to lift at 4. It took one full turn for it to lift at 4. It now hits the stop at 19. Still getting overboost at high rpm wot.
Requested boost maxes out at 2050mb and actual is approx 2500mb when the limp mode hits. I had seen the actual boost hit 2599mb when the actuator was lifting at 3, I guess this is the limit the 2.5 map sensor can read. So it does seem to have dropped a bit.
Do I need to lengthen the actuator a bit more, maybe to lift at 5? Or is this a normal situation when a vnt17 is installed and the ecu still think a vnt15 is installed?
Any info appreciated.
