Hey guys just got my 2016 fiesta st not too long ago and the car is now throwing a underboost code (p0299) and is running absolutely awfully so immediately I checked my charge pipes and there wasn’t any popped. And then I decided to start checking vacuum lines and couldn’t find anything there either. Cleaned my throttle body and MAF and nothing as well. The car does have an aftermarket turbo and downpipe and exhaust. My next guesses would be boost control solenoid or a boost control sensor. And no the car is not blowing any kind of smoke and there isn’t any oil in the intake system or any oil coming out of the exhaust. Could use a little help here considering I’m new to the community. I also attempted to check the wastegate to see if the rod coming out of it could and would open and it would but that still doesn’t mean it couldn’t be messed up right ? Just want my car running good again it was so much fun while it ran right . Any suggestions or help will mean the absolute world. Thanks
