Fuel Pin Spring?

[lincoln]

Does it hurt to run without this spring? Does it help fuel mileage? A freind told me that if you take it out it will help fuel mileage and power a little bit. I took it out and drove a few miles but dont realy feel anymore power. It does smoke a heck of alot more.

put the spring back in, you,ll hurt fuel ecnomy with out it but wont get any more fuel on top end, full boost. i like the red green softer spring vs the black green or red. accelerates harder when boost hits. grind fuel cone or afc lever or aftermarket cone (pin) for more fuel. or remove afc lever.

I put it back in. The little trip I made today normaly wouldnt burn but 1/4 tank. Today I used 1/2 a tank. I have a red/green spring in it. Thanks, next time I going with my gut.
