--2016 w/DHM turbo kit
Hi All,
I started running into an issue under load in 3rd-4th gear at around 3500-4000rpm where the car falls flat on it's face, STFT goes through the roof (usually +30-50%) and boost cuts out. Basically all the signs of a boost leak. Then the car sometimes takes about a mile to recover to normal operation and STFT stays very high...I'm assuming due to some temporary limp failsafe in the ECU, or maybe the leak induced takes that long to seal back up.
Now, that second part has me thinking the leak could be pre-turbo inlet and unmetered air is getting into the charge system rather than boost pressure causing the leak. Just gut feeling.
I noticed on my CP-E intake the PCV breather hose connection didn't seem to seal well (see below). So I removed it and now am running a MAP intake which uses the factory crossover pipe and I still notice the hose doesn't make a very good seal. Myself and a shop have gone over all hoses from air filter to throttle body and insured all clamps are tight. My next step is to do a boost leak test using compressed air, but I wanted to ask here first if everyone else's breather hose is loose feeling at the intake side, if anyone has engineered a better way to seal that connection with a thicker o-ring, etc., or if I should look into ordering a new hose assembly.
I don't have any codes being thrown or pending.
