I have a 2003 Silverado SS. It’s LS3 swapped. Has a TRG module. And I’ve been having trouble locating a tuner willing to tune my truck.

Why is that?

Is this truck setup I have able to run a flash tune?

Other than swapping the crank out. I need to find a reliable tuner. One familiar with LS3s and the TRG-002s.
