After the Programer and intake on my 6.7 its feelin kinda fast and I want to try out my new upgrades at the buck this weekend. I am only planning on doing the drag racing this time though. What will i need to have to be able to race. On the site it says a 2-1/2 lb. dry chemical fire extinguisher, and a helmet. Is this just for pulling or raceing to I have the helmet but not the extinguisher.
