Best Detroit DD13 shop near Savannah GA, lost an injector today

Title says it all, currently down in Jacksonville FL , but have a load to Lubbock TX tomorrow, and the injector is failing. Can dump the load.

Code is SPN 4258 FMI 4

493K on original injectors.

It's not a pin issue, I've already checked them with the meter. #3 in injector is just giving up the ghost, so which is the best dealer between Savannah and Jacksonville?

I could limp it at derate up to my home base in Norfolk Va, Excel truck group in Chesapeake, VA.

 

2020 freightliner, GHG-17 motor, so new injectors have to be programmed by a dealership.

 

I'll keep checking till tomorrow, but if nobody can recommend a good east coast Detroit Dealer, then I'll limp it to the dealer...
