I have seen alot of post with people saying that their piped and jetted Raptors seem to be starving for fuel on top end. Before you go re-jetting thinking it is lean try running it without the airbox lid. You could be starving for air instead of fuel. Its worth a try isnt it? A wise man once said..."Give an engine what it needs not what you think it needs." Whatever that means...hehe

 

Digs,

You're correct and this was mentioned in my post yesterday..."Big Gun JETTING Dialed In".

 

Cool! I wonder if this would help a stock Raptor.
I think I will try it.
