2009 Silverado 6 cyl Engine swap to 6.0 e-force SC setup issues

[mowton]

So we have had this project in the shop for a while and just can't seem to get it right. Long story short, customer had his 2009 6cyl swapped out with a 6.0 and worked transmission. Wanted a SC installed which we installed with an e-force kit and utilized a 2007 E38 ECM with and ....4088 OS file. Had tranny issues and eventually installed a TCI controller which works ok at this time. We disabled all the T42 TCM torque management values and all seems good with that portion. Had exhaust restriction issues and installed a new ARH system from LT's to hi flow cats.

The main issue is the truck just won't go to boost levels and maintain proper fueling. Have monitored fuel pressure and it holds the 58 lbs. Can get into some boost levels but at certain point (see logs) the fueling will go from right on to about 10-12% lean to >45% lean :-O. It appears as the the transition from good to 10% lean begins, the Bank1 and Bank2 IPW's begin to diverge. This was proven in the log as well as with a tech 2 via the narrowband infromation. For some reason, Bank 2 leans out.....we have checked and double checked the wiring to the injectors and all seems well. We have even installed a second set of injectors (went from siemans 60's to Fast 52's which came with the kit) to see if that cured it with no luck. For some reason, and I hope we aren't chasing our tails, the PCM thinks that Bank 2 inputs are different than Bank 1? The tune is in Open Loop Maf now, but we have tried Speed density with the same results.

In the attached logs (PE was set to .69 for test purposes, normally it is .75), here are the key time stamps: ..am 4 after... -- 12:14:18.69, ...am 5 hold tranny... -- 12:18:55.227 and ...am 3 after... -- 12:10:24.178 and 12:10:51.627.

Any help in this situation or a place to look would greatly be appreciated at this time. Thanks again and hope a new set of eyes/brains can help us send this project home.
