yes the spring can go weak in the actuater, have you got a aftermarket boost gauge fitted? i wouldnt pay any attention to the standard gauge.I already have a 1 bar forge actuator fitted, im not convinced im getting 1 bar though. My external boost guage shows 0.7. Was on the car when i got it but car was garaged for years. Do they wear out?
Yes the guage is aftermarket. How easy is it to change the spring? Could i do this myself? Im no mechanic hahayes the spring can go weak in the actuater, have you got a aftermarket boost gauge fitted? i wouldnt pay any attention to the standard gauge.
