Hi looking for some help.my 2015 is losing boost pressure wont make more than 5psi. I shut off truck and restart and boost comes back for a bit then it loses boost. hooked up scanner and it say air leak between maf sensor and intake. i'm thinking the code is coming up after loss of boost. after restart I can make 30 psi of boost.

 

After that restart, are you able to continue getting that much boost or does it fall flat again? If it falls flat again, you may have either a loose clamp on a charged air line, line split, or leak in your intercooler. If you continue to have up to 30# for the rest of the drive, you may have a sticky waste gate.
Back to morning brew . . .

 

Hi thanks for the reply. the truck keeps boost you never know when its going to lose boost may take a hour or a couple days. I have not had any issues with the e brake
