There's not one for the Sidewinder, however, I know for a fact the CES + RAMAIR is going to be closer than a best guess done by Hanso. Not knocking him, but, educated guesses vs actual dyno time. The CES + Ramair tune I posted was in the 13:1 region at high RPM, so, the Sidewinder setup willl see mid-high 13s, a little leaner than optimal, but still completely safe.
All tunes should be considered base-line tunes until strapped to a dyno and adjusted.
As an example, of why, when adjusting the valve tolerances on a rocket, only 2 intake valves were changed on clyinder #3, same intake, same dyno, same pipes, same cams, same tuner, the fueling was significantly different, more than a 10% adjustment in fueling was required.
Now imagine the tolerance differences, cam timing differences, ring sealing differences not to mention dyno differences and I will never endorse throwing in a downloaded tune and calling ti good
