Why yes I am getting that kind of gain. But in additon to the Borla and FIPK2 I am using an Tornadoe and 13mm wires. How to get an hotter spark when I return to the beach. We have an dyno at the shop on base. Borla stated I could reach as much as 25 . So for both parts it was an gain of 33 and about an 1/4 of tank . But I am getting ready to upgrade tires to BFG 31 and I expect to loose all of that .
