Everything worked just fine. Stays in V8 mode and so happy! Thanks again!!

Has the problem been corrected? When will a update work with the truck?

Please let me know also when someone has the correct update or solution to this problem. Been back and fourth with different updates and even tried a custom tune.

I'm using the trinity 1000 , how do I pull up a backup ?

Installed diablo tune and turned off dod/ and still going into 4cyl mode. Truck also feels sluggish.. am I doing something wrong or am I missing something?

Any Updates?

Any updates for the 17 silverado 5.3 6 speed?
