im having this stupid problem in 5th, the car drives perfect in every gear. only boosting to .7 bar, and holds it very well. apart from 5th, if a plant it in 5th itll hold for a few seconds then just start rising and i have to let off. but it doesnt do it in 4th, im going to fit a bleed valve to get rid of the amal valve this weekend, anyone have any ideas? using a turbo technics actuator by the way.
