Hi guys,
I have just this week fitted a gtb2260vklr and firad 80%+ injectors to my car... the car wasn't making requested boost (underboosting) up until 3500 rpm and made 327hp/377lbft but only over 1000rpm rev range till the limiter. I tried playing with N75 map but trying to close vanes earlier didn't seem to really help.
Today we played with the actuator arm slightly and shortened the VNT and boost is now kicking in at about 3000rpm and it pulls nice till the limiter but still very laggy considering it should be able to make 1.4 bar at 2400rpm and after the adjustment actuator is now hitting the stop screw at around 15" on the mercury gauge.
Just wondering what anyone with some more experience would recommend?
Vacuum and actuator hold pressure so there is no problem there... thinking to run basic settings in measuring block 11 tomorrow to cycle the n75 valve and see what the solenoid is pulling on the gauge to check that is healthy.
I will try and get an EMP gauge to hook up to the EGR blank and then maybe some stop screw adjustment may be required too...
