Topic: Shims needed based on nitro%

After reading in the forum I think that the C6 BB ships from the factory ready to use 20-25% fuel. Do I need to shim the head to run 30%? If so what shims do I need to remove or add?
thanks

MOst people will tell you to just run it, i personally broke my ws7 in on 20% nitro and then added a .1mm to make it a total of .4mm and went to 30%. i hardly had to touch the needles after that and im on gallon number 9.

It is possible to run 30% nitro with the original shim setting but it is safer to add 1 shim of 0.1mm
