I've just picked up my new truck (in signature). Previous owner was running the TNT tune. I kept the smarty I was running on the old truck which has the Revo tune. Drove the truck home with TNT sw9. Very fast very smokey and very responsive. Based on reading various posts regarding less smoke, I switched to the Revo sw3 TQ-2 RP-2 TM-0. I am not very clear on what "timing" actually is. Basic understanding is that is when the fuel is injected into the cylinders? So more fuel with the DDP 90s would be advancing/extending the "timing"? Does this increase egt due to more fuel? I am looking for a good mid level tune with very little smoke. I never ran more than sw3 on the old truck because I did not have gauges or a transmission that could take it. Thanks TDR I have learned a lot here and am learning more.
