Just went out and did this, they are adjusted properly and the servo is functioning like it's supposed to. Still running like a piece of $hiz on the bottom end!

Seems like its starving for fuel
Kinda bogging out

Hopefully you get it figured out. Let us know what it is

sounds like reeds need to be inspected might be broken

Pulled reeds a couple days ago, they still look brand new!

Compression test it. If that is good move next to tying in a gauge to watch your fuel pressure to make sure it is not dropping off and after if that is not it maybe ohm out your stator or get it tested. It's not throwing any codes? I had the same thing happen to me off and on and it turned out the servo motor was screwing up.

Reach in side of the tank and pull up the fuel pick ups. They might be plugged off. My brothers was doing the same thing and it was his fuel gauge that fell apart, and the peaces of that was holding the fuel pick ups out of the fuel.

Well I finally figured out what went wrong.. ECU is buggered! Swapped the ECU from a 2010 M8 and the sled ran perfect, and the 2010 with my buggered ECU in it had the exact same symptoms (aka ran like crap)! Probably won't be cheap, but I'm glad to have it finally figured out.

There is a guy parting out a 11 m8 on kijiji in grande prairie. You could see if he has the ecu still.

That's good it's figured out
