Hey guys my tach jumps all around from like 3000+rpm when u really hammer into it. The tach will go to 5 then 2 or 3 or 6 then to 3 anyways it jumps all over the place. I look at my monster tach and thats does the same thing. What do you guys think it could be? Possibly my coil or crank sensor?

you dont have a crank sensor. pull codes. look for PIP or IDM codes. good luck.
