I have these 3 codes pulling, nothing leaking. everything is great with driving until I’m up at 60mph and give it full throttle, it throws it into limp mode almost everytime. Does anyone have any ideas what is causing it to read boost pressure to high and boost pressure shut down.
I’ve had this car about 3 months.
It does have an MHD stage 2 tune from the previous owner, index 12 injectors, after market dual exhaust, and a blow off valve, with catless down pipes and a muffler delete.
