[Bhullargp]

Hello everyone

I am an owner operator and i have a peterbilt 379-2007. I recently had my issue with pyro going very high and making the red light come on many times and i went to mechanic he told me to get a new turbo. I got new turbo installed but my pyro was still going into red then he did some fixes and the pyro stopped going into red but now in hard pull it reached up to 10 or 10.5 normally runs 7-9.

The main issue since i got new turbo is my boost it doesnt go over 25-28 in hills. I drive in British Columbia canada. My back pressure for jakes at high also doesnt wanna cross the same 25-28 psi. I also replaced air charger cooler cz there was minor leak but no change in boost even after spending all this money.


Please help me
