No, I did not tune out vvt. From what I read it should still be able to run without it, it'll just lose some torque/power. I can see how that would make it not run correctly, but why would that cause the faulty MAF readings? -
Did you tune out the VVT? 07-09 they did not have VVT. 2010-2013 they did. If you haven't tuned it, its trying to adjust cam timing. -
GMT-900 is not Global A.

These show the problem and symptoms, and I explain things too. to clarify again, I did not change over any computers or wiring (with the exception of the map sensor). All of the computers and wiring are original to the 2010 vehicle video 1 - background info/explanation and part of the problem video 2, idle misfire I think the reason that the MAP sensor is reading High is because the engine is misfiring so there is less vacuum... Additionally there's a p0102 for the MAF low frequency, and a p0108 for the map high voltage. Again, apologies for the somewhat long-winded explanation, it's a rather difficult problem to explain without going into the details. -
You'd want the Pulsar to be safe. That was the first product that worked for 10 speed trucks that they came out with. Range Technology 22451 Pulsar LT for 2019-2022 GM Gas Trucks That said, in the features description of the RA003B, it does list it working with 10 speeds. However there are reports that the RA003B can cause some drivability issues on early 10 speeds. So the Pulsar is the safest move IMO. Range Technology RA003B AFM/DFM Disabler Features: Range AFM/DFM Disabler keeps you in full power 100% of the time Simply plug into your onboard OBD-II port and it instantly begins working to eliminate the AFM system Disables Auto Start/Stop Blue LEDs The Range AFM/DFM Disabler does not reprogram factory ECU Works in hundreds of applications, 2007-2022, including 10-speed models.
