2011 GSR hitting fuel cut: WTF?
Running stage 1 93 octane Cobb map. Bone stock. Should this be happening? Anyone else? I've only noticed it tonight, as the temp has dropped a bit. Severe buck in high rpm. What can I do about this? I thought the AP would delete the fuel cut. Any help is greatly appreciated. Thank you.

So I'm out for a drive this morning and the bucking appears again while I'm monitoring boost level on th AP. this time the SES light came on and the code was waste gate actuator failure. Boost was only hitting 27 PSI, but I'm assuming the solenoid duty cycle was beyond the limit? Is this a fair assumption? I saw some low waste gate duty cycle maps somewhere available. Would these solve my issue without killing power? My car is stock except for the tune. Outside temp per the readout was 36F. Last night was probably in the 40s. Is the bucking fuel cut or just the solenoid taking a dump and instantly dropping to waste gate boost? Sure felt like fuel cut.
Off topic: I got a possible Icy roads warning. Is it temp driven or from abs picking up slip?

Probably not the case, but did you check this;

That sure sounds like a fuel cut to me. I don't think it's the traction control or the hose .
Take a look at the below link(post 993):

So I finally had some time to run a log or two and analyze what was happening. I was definitely hitting fuel cut. I increased the values of the load limit and load delay tables using ATR and hopefully that will solve this issue. Once the wife gets home to watch the kids I'll go and log a few runs. I was wondering if there was anything else I could do or if I missed something? Thanks.

make sure you hold traction control for 3 seconds to shut it all the way off my 2011 does the same thing when its cold shutting tac on seems to do i think its the tires trying to break free

Every car is different even if they roll off the assembly line after one another. Some people have trouble hitting target boost while others fight over boost conditions. It's just luck of the draw. I didn't get a chance to thoroughly test but it seems my issue has been solved. I did spike 28psi today so I'm wondering if the changes I made effect max psi as well? Is 28 psi relatively safe ? Load reaches into the 280s. Is this ok?
