you lost me at $8.29 a gallon! haha
as far as the traction example, or lack of traction, after the Sunoco was added could be attributed to being on a different pavement. I know in my Z depending on what kind of surface I am on dictates how much wheel spin is generated.
im not saying your butt dyno isnt calibrated correctly, im just saying that pavement could be a contributing factor.
