Tuning in NJ for a 2015 Silverado?

I have a 2015 Chevy Silverado 1500 with the 5.3 and it has that annoying AFM feature where it switches from 8 cylinder mode to 4 cylinder mode. I bought the RANGE AFM Delete module thing you stick in the OBD port but I have found it drains the battery when the truck sits for more than a few days and every so often I get a no start condition with a P0700 & U0100 code. I suspect the RANGE AFM Delete has something to do with it but I am not 100% sure. I would just like to find a local tuner that can delete the AFM, I don't really want any other modifications to my PCM.

Does anyone have any suggestions of a reputable local tuner?

I think either of our sponsors EFXtuning or JSPerformance could help you

The looser the waistband, the deeper the quicksand. Or so I have read.

Feather-light suspension, Konis just couldn't hold. I'm so glad I took a look inside your showroom doors.

Hey everybody, it's good to have you on the Baba-too-da-ba-too-ba-ba-buh-doo-ga-ga-bop-a-dop
