I just took the truck out for a test run after doing the tone ring mod. All I can say is this is how the truck should have run from the factory. Before if I goosed the throttle there was a bad hesitation and then it would come alive. Same with accelerating. it would be real slow to accelerate until about 2200rpm and then it would come alive and take off. So it had a real narrow powerband and real uneven power curve. Now I can tap the throttle and the power is there instantly. Same with accelerating. It has a nice and smooth curve until the top. So in total my mods now are the silencer ring and torque tube mods. muffler delete so I have a 3.5" straight pipe and now the tone ring mod. I hope all this makes for a fun truck that gets decent mileage.
