i was doing some reading and i was reading about having to add or remove shims depending on what nitro content you are running i have a picco with stock head shims and I'm running 30% nitro do i need to add or remove head shims? cause I'm trying to get a tune on it so i can get a gallon of fuel through I'm not trying to do a performance tune cause I'm still in the break in process, i just want a good enough tune so can get a gallon through it, or more. but i was wondering about the head shims.
