Have encountered a slight issue , wondering if anybody has got any ideas.
Out driving on sat night when i floored it and suddenly hit boost cut. Looked on my EVC and saw i had spiked to 19psi. Turned down the boost and gain and same thing happened. Had a look at the turbo yesterday and put a hand pump onto the actuator and it didnt open till about 2.2 bar. After it cracked loose it would open sometimes at 7psi sometimes at 10psi. Took it back out for a test drive and the first couple of times it would sit at actuator then it would just want to keep boosting. I checked to see if the wastegate flapper was fouling on the new downpipe but its clear. All the big UK supplier of greddy/mitsubishi turbo parts has shut for xmas now. Do you think i will be able to buy a new actuator as a separate piece for this and do you think my diagnosis is correct or do you have any ideas what else is worth checking? Didnt think actuator failure was a common occurence.
My car runs about 12psi of boost so do you think it would be preferable to run a higher rate actuator if one is available or not worth it?
