Default Help with no boost logs attached - 04-11-2022, 02:56 PM

Sup friends,

I recently wired on my DP fix and removed it. After this I got an issue where I'm getting no boost at all. Exhaust sounds louder as if the wastegates are all the way open. I removed my jb4 completely and flashed the dme back to stock and the issue remained. I wired my jb4 back on and took some logs. There's no sound of the turbos even spooling. Any ideas of what this could be? Could it be DME related?

I attached a log. ECU PSI and Boost values pretty much stay at 0 for the whole run.

I don't think it's a boost leak since Im not even getting any spooling noises and it pretty much happened over night. Chargepipe and intercooler connections are tight.

Getting a 2DED and a 30FF code
Mods: DP, relocated inlets, jb4, wagner IC

WGDC is completely maxed out and no boost.

Sounds to me like your boost solenoids aren't powered, or the vacuum line to the solenoids got disconnected somewhere.

Boost solenoids were it. Thanks for your input gents.
