I put the thicker of the 2 back in and had too re tune engine. the head temp went up some but the pipe is still hotter then the head. I am running sidewinder 30% with os#3 turbo plug and a dynamite 086 pipe. also I am not using temp gun to tune just to make sure I am going in right direction. One other thing, the engine after fully warmed up and tuned in was easier to drive. a LOT more controllable power. I know I am new here but I would like to say thank you to all the regular's of this thread. You have no idea how much I have learned and am still learning about this engine.
