I thought I'd post my tune here since it's R3/R3, seems easy to drive (at least with a wheel), and I'm fastest with it vs. a R3/R1 or R3/R2 tune.  I've only managed a 2'12.092 with it, but then I'm never the quickest, and usually run nearly 1.5 secs/lap behind the fastest guys.  So, this tune seems good (only .8 or so back).  This is a TwistyTune(c) in that I still believe PD has the spring rates reversed, front to rear, so in this case the rear is stiff, which matches up with the R3s there.  It's a little new so I'm sure it can be improved on and maybe someone can break into the 2'10s or, did I miss someone already doing that?
