I recently had my Mk4 Golf AUM re-mapped by Custom-Code. Been reading various threads and info on the net, and apparantly the factory Actuator is adjusted to match the standard boost. Now that its running over 200, to get the car to boost at increased PSI, would require the Actuator to be slightly adjusted. How would i go about adjusting the Actuator. I heard you only need to turn a couple of threads at a time (on the wastegate settings/locknuts) max and mark the original position, too much and it could blow the turbo!! Any more info on this? Also, has anyone adjusted theirs and noticed an increase in boost. Mine seems to feel underpowered the last few days. Could be due to a faulty N75 valve perhaps.? Ive heard that you can adjust the amount of air which should leave the N75. Is this also true?
