Tune with race gas, then use tune for WI?

[bishiboy]

What if I tune my Evo VIII with race gas then use this tune for WI?
It would solve the problem of WBO2 readings. Generally the race gas tune would have the same settings, leaner mixtures (12.5:1), increased boost and more timing.
I think if you do a conservative tune on race gas and use it for WI it should be pretty close.
Any input on this?
By the way, I have a UTEC. I already have a good 91 octane tune on map #1. I can set up a race gas/WI map in another slot. If I run out of water, I can switch maps.
By the way...I love this UTEC.
