I can't turn down the boost. I know its not good for the car, I'm just wondering if there is any danger of cracked ringlands, BHG, etc. because of fuel getting cut off. A/F stays at 11.0 or so until fuel cut.

Thank you.
Just wondering, Couldn't I just hook the ISC hose to the intercooler pipe instead of the accordion and not worry about the diaphragm anymore?
Is it possible they are stuck or went bad? The rings are NPR.
The smoke is the worst under high rpm/closed throttle
Stock PCV system.
There is no smoke on startup.
The smoke got super bad even just idling, so I took the downpipe off to check for oil and it was dry. I started it open turbo and revved it, there was no smoke at all. I went out driving with just the stock elbow on and there was no smoke for a while and suddenly it started pouring out again...
My 7M has about 5000 miles on a fresh build. It would blow a little blue smoke on decel from high rpms but was otherwise fine. I upgraded to a DM 57 trim and the smoke didn't change. I drove it for a few hundred miles and suddenly the car started pouring out huge clouds of smoke on decel, enough...
Starts fine until it gets completely cold in the morning.
Cold idle is perfect.
CSI is hooked up.
I'll try jumping the fuel pump and see what happens. I already have a new 255lph pump I'll be putting in, so I'm hoping the old pump is the culprit.
My 7M recently started being hard to start when cold. It will crank about twice as long as usual before stumbling to life at 300 rpms. No codes. Wideband still reads rich after it starts (~12.0). Any ideas?
Temperature is about 40 in the morning when this happens.
