Lnf turbo wastegate actuator
Loss of boost (limited 5lbs) rough cold start 25% throttle when i put it in gear it wants to stall.
Possible Limp Mode?
ran check engine light p0243 waste gate actuator solenoid A
I pulled it off and it wasnt very strong couldn't hear the click and barely feel the click so i bought a new one still didn't help but before i would spike to 15lbs and drop in 3rd-5th gear now its strictly 0-5lbs.
Wires looked good connector clipped it off no problems took a power probe to it read 14.5 and 3.5 while the car was running
Vacuum line pressure test on the bpv and waste gate both hold 25lbs fine.
Unhooked battery to do a clock spring and that didn't fix much.
I haven't pressure tested the turbo because i'm pretty sure it wouldnt be a leak it seems as if the wastegate is just staying open.

im having same issue but if i pull the hose off of the wastegate and plug it i get full boost im thinking lower map sensor or some other reason wastegate is prematurely opening . if any one can shed some light on this matter would be greatly appreciated ...
