I am getting the right side intermittent not staying on issue too. I just unhooked the resistors and set the truck to rear LEDs. I have an ECRI programmer and it does have a voltage threshold setting anyone mess with that? I do not have the turn off diagnostics setting though.
I ran a moroso on my 5.7 charger primarily to keep the tune from backing off. The oil vapor would cause the timing to back off from mild detonation thus losing power. It worked great and the intake still looks new inside after 130,000 miles. I will be repurposing it onto the JT if nothing else...
