Thinking of putting the 2.93 Lightning pulley thats on my Cobra right now on a Harley pickup which I think has a 3.19(correct me on that if I'm wrong). How much of a boost increase will I see and will it require a retune?

Before I get scolded by the search police I did a search. Looks like 2lbs of boost difference and no need to retune. Correct? :thumbsup:Will the stock
HD belt work or do I need a Lightning belt??

The stock tune CAN handle up to 4 psi over stock. A retune isn't a bad idea but in this case isn't necessary. The belt may work, you'll find out I'm sure.
