A little different tune, i havent changed a lot of my tunnel tunes and still competitive. SSRX gearing is a little longer then SSR7
For regular cars (no aero trick) a tunnel tune in ssrx should trap about 2 mph faster
Aero trick exceptions
speed 12 goes from 240's in the tunnel to 258
z06 rm does 259
zr1 rm only did 236ish in the tunnel, much more in ssrx I just forget
no stripe and cien with wing gains more then 2mph and are faster then ones with no wing
The extra distance give it room to catch up from a bad launch
