For the last couple of months I’ve noticed my 2016 fully deleted DRD tuned w/MM3 truck surging badly at anything but nearly full throttle. After watching the position of my turbo blades % on my monitor it seems as if at light throttle they will not hold position and fluctuate wildly.

Some days there is no surge, trucks runs smooth and has plenty of power. Other days it sounds like it has a big cam and the surging comes through like I’m pumping the accelerator.

My truck only has 60,000 miles, I’ve never let my egt’s reach over 1,200°, run my exhaust brake 90% of the time and don’t shut down until egt is less than 400°.


I’ve googled the crap out of this subject and no one seems to have a definitive answer. I would attach a video if I knew how.


Hoping someone has figured this out, if so HELP!
