Hey everyone, it's been a while sense I have bee on here. I have a 2012 6.7L. I'm running the edge CTS screen so I can monitor my vitals like egt,Trans temp,coolant temp, boost ect. So now my question. I can be going 60mph down the hwy and look at my cts and my boost will just drop out. So from 6-8 psi at cruising speed to 0.0psi. I dont care that it says i have no boost when i can tell i do. My issue is if that isnt reading right the my exhaust brake doesn't work like it should and im headed to Wyoming saturday and would.like it working properly for my trip
I was told the MAP sensor. Changed it, didn't solve my problem. Talked to my efi live tuner, he said that the edge screens can pull to much voltage out of that circuit and cause weird things to happen. So I pulled the CTS cord out of the obd2port and still the same issue with the exhaust brake. So then I unplugged my CSP5 switch. So now there is nothing in the OBD2port. Still have the issue. Looking for any ideas. Let me know what you think. And A THANKS FOR YOUR TIME! I have a video of it I will post it on YouTube and share the link on here.
