U7193-2005 GMC 6.0 2500
Running the latest predator version and am looking for who's running what set-up..
Truck is completely stock except for 295 tires...
I have put in the predator tune with firmed up shift points....it has a little more power but stills seem doogish of the start and when u come on to it, it doesn't drop down a gear and go....can someone tell me what parameters they have set to for best results? It struggles pulling a trailer...
