MK808BT
I have the MK808BT and use it for my 2018 Chevy Silverado 2500hd Duramax and it has saved me a lot of money from the dealership from needing forced regens, injector pigtails, nox sensor, Def injector and hood sensor causing the alarm to go off while on vacation at Disney World. So for $89 for the update is a no-brainer vs the $150 . Thank you OBDPRICE
