does the fpr mod produce more smoke also I tried to go to diesel innovations to order one but there isnt a button to add it to your cart, does this mean they are not in stock or something???????about how much do they run?

I seen it, cant you just put a bb in it for the shim? Somewhere in a post, it was said that the bb fpr shim would work in all 7.3s.

a regualr BB from a BB gun works great and cost next to nothing. It will not really increase power or smoke very much by itself but usually does help it run better, especially with modded trucks that burn more fuel.
