This is what happens at Gintani.. The lower number is from when i had only a generic tune. Afterward I got the custom tune and these were the results after 20 pulls.

Mods at the time:

Gintani rear section
Catless Stock midsection
RD Sport Pulley
Macht Schnell Airfilter
RPI Scoops
Gintani custom tune.
