Would you run your smarty on 2 or 3 on the injection timing on the tnt-r with flux 2's, just curious if anyone has tried it on the dyno and if you get any difference. Thanks for any input.

 

With your 05, even with the Flux 2's, you can most likely run timing 2 with better results than timing 3. All trucks are going to respond differently, you just have to try them both and compare.

Most 03/04 trucks cannot run TNT,TNT/R on timing 2 without bucking and popping, even with stock injectors.
