The incrementals are pretty much inline for a great [chassis/setup efficiency] The second half mph is about 1 mph low though, no biggie. You should be picking up around 25 MPH vs 24 MPH.
My ride picks up 26 MPH witch is about 1 mph high IMO But Im more aerodynamic with my Abody.

You do have traction issues as you already know. I like the input of the DA vs ET, lean vs rich.
