Well before letting Racechip start working their tune magic I thought I would be fun to get a baseline dyno test....
And it was a hoot, scary as crap with a rig I need to put into the SEMA show in a few days but still fun.
Not that I am aware of, I am current 10mph off by GPS, 18% by tire calc. I have done some long distance testing and the 18% seems good.
After SEMA I will be looking deeper into the speedo issue.
