I am in NC, RPM Motorsports in Garner NC are well respected by the GM Corvette and other GM vehicle performance crowd. I took it to them and they found 4 injectors in bank #2 to be out of spec, but I asked them to stop diagnosing as it was on my dime. Entire bank of injectors is most likely not defective but rather there could be issues with vacuum on bank #2 or with running too rich and O2 sensors. Folks here are telling me that injectors cannot be failing without a code due to strict emission controls in the truck but RPM Motorsports guys found bank #2 to be 30+% out of spec on the injector balance test and zero codes... How is that possible, I do not know but I posted RPM results here, they are confident on their findings. RPM told me that to really find out what is wrong one needs to do leak down test, etc. I was already $300+ in rental and mechanics fees, I stopped in hope that diagnostics from RPM will be enough from GM dealer to fix but no dice... no codes, no issues per the GM.
Hey Dmitry, where do you live? Why not get with someone more knowledgeable about autos and have them check it out with you? Live in Florida by chance?
