Default 2 PCMs, one for 110 one for 93???

Just wondering if any one has done this? Had one PCM tuned for the street with 93 and one tuned for the track with 110?

What do you expect to gain from running 110 octane
on a stock-compression motor? I am not seeing ping
on 93, with 243 heads (half a point, or so, higher CR).
110 might just be expensive and perform worse.

You wouldnt need a second computer. You could just flash a different tune into the car. Im not so sure you would benefit much from it anyway.
