did u get a dyno sheet? i did its just to light can't read it. I ran one tank today wrapped the head alum. tape and putted back and forth on the street max 3/4 throttle. temped around 195-210. much power even rich like it was. Two more tanks and I will start to lean it out a little. I ran the p4 plug. THe only thing i didnt like is I don't have my Big Bat muffler LOL.
