Alright guys, looking for some help. I have a 2017 Sierra 6.2 w/ Whipple SC, TSP Longtubes and Alkycontrol.com meth injection setup. I had the blower installed in Dec 2017 and its been running great. Its the wife’s truck, but she has a company car and it has been sitting more than its been driven over the last couple of months. Last week I started getting a bunch of DTC codes. They cycle but when cleared when they come back it doesn’t seem with any regularity or predictability. Here is what I am getting:

DTC Codes
-P0650 Malfunction Indicator Lamp Control Circuit
-P1682 Ignition 1 Switch Curcuit 2 (Faulty Ignition Switch, Ignition Switch Harness open or shorted, Faulty ECM
-P0017 Crankshaft Position Correlation
-P2227 Barometric Pressure Sensor A Range/Performance
-P2228 Barometric Pressure Sensor A Low
-B2111
-P2136 P2136 throttle/pedal position sensor/switch A/C voltage correlation
-P0611 P0611 Fuel Injector Control Module Performance

Anybody seeing similar symptoms?
