Codes popping up
Everytime I'm hitting around 5500 with my setup my car almost falls on its face and sputters until 6500 then let's go.. I got ecs blower and direct port meth. I started the car this morning and 2 codes popped up

Ya, this started happening a week after the tune, I thought it was low meth but it's not. I have a guage on my fuel rails for the direct port meth and when I test it it only reaches 20 lbs on the guage. So maybe it's the pump going bad after 400 miles

Car has to be running. I know you were dynoed on a hub dyno that can be generous but nevertheless your at 685, your lt1 fuel system has got to be at full tilt. Maybe your running out of fuel at 5500 rpm. You have got to be at that fuel systems limit. Ecs definitely knows what they are doing so I’m kinda at a loss? But if your getting green light your at least 50 psi and meth is working fine.

Neither of those codes should effect drivability, those codes are not in HP tuners software, but here is what came up when I googled them;
Lumbar Down Switch Failed
Definition of check engine code B2111:
GM:
Lumbar Down Switch Failed
Reason For C1151 Code
The reason of C1151 OBD-II Engine Trouble Code is Engine Oil Temperature Sensor Malfunction.C1151 the main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit.

I had a very similar issue with my car falling on it's face at 5200 RPM. I didn't have any codes, my tuner could see a slight missfire. We upgraded to a custom set of Granatelli Wires and BAM! Solved the problem. MSD Wires were the issue..
