I was just teasing about the signature!

I do see that there are 2 years between your dyno sessions... so that could possibly explain a few of the HP depending on mileage and maintenance. I would also expect that the installation of the ring and pinion could eat up a few HP depending on how its shimmed and the gear mesh?

it all has to do with load.. I ddn't get in to it fully with my tuner..difference in Milage is about 20k and Maintenance is performed every 3 months oil changes..i think that any who does a before and after dyno after gears will have the same result.. as my tuner said don't get hung up on numbers it just a before and after result with mods or tuning.true number are made at the track.. which is where im heading this winter..
