i’ve been pulling my hair over this and i can’t figure out this boost leak, all i did was a thermostat upgrade and never touched no valve systems, couplers, hoses, and i have checked everywhere no major leaks, check each individual hose, but i don’t have access to a smoke or pressure test. But the weird thing is i should be @ 23ish psi for the turbo but only pushing 16-20. and when i lay on the throttle and it peaks out 16-20psi like 2 sec after my turbo starts spooling i hear another spool(the leak) on the drivers side firewall right by my ecu?! it sounds like it’s literally outside the car, no it’s not my charge pipe or pcv valve system. and now after a week of driving it carefully and small distances since i can’t get to shop in time my check engine light came on and threw code p0128 so the leak has to do with the engine over cooling? PLEASE HELP
