Run a FULL can of SeaFoam in 1/8th tank of gas....run it almost out before adding new gas. That will clean the fuel system better than anything, including the injectors.
Clean the MAF with MAF cleaner........spray the IAT sensor in the lid while your at it with the MAF cleaner.
If that doesn't do it....your issue sounds exactly like a failing 02 sensor. Of course make sure none of your spark plug wires are touching any part of the metal exhaust piping....that will cause stumbling at different rpm's.
But I say it's an 02 sensor.
Ae you using more gas than usual.....?

Solved!!!
Well after I installed the longtubes and ory, and had the pcm tuned by frost, the car runs 100% better! No more weird bucking at 1500 rpm's, and no more falling on it's face when you jump on it. I can't be certain whether removing the cats solved it, or having it tuned but either way...it runs the way an ls1 should and I am super pleased

Yeah, longtubes ftw! However, I did commit a longtube install no no. I didn't put poly motor mounts on while I was in there, and guess what! The collector flanges are bumping the floor during hard acceleration. Oh well, I'll just deal with it for awhile until I redo the exhaust for the GMMG/CME install
