I have a 1999 VW beetle 1.9 tdi ALH it has a stage 2 bosh pump newer injectors new timing belt egr delete and new clutch. I bought the car with a bad turbo the vanes were stuck so I replaced the turbo and actuator. After replacing the turbo I noticed the car ran better through town but still sluggish so I adjusted the actuator using a mighty vac now it has plenty of power around town but still goes into limp mode at 70 mph. I've checked for boost leaks and everything is sealed I've checked the N57 valve and it seems to be fine and all I can get out of it is P1550. I don't have a computer to use VAG-COM on so any help would be greatly appreciated. Thank you
