De-tune would be retarding the ignition timing to compensate for the compression ratio & fuel octane mixture, otherwise you would run into detonation issues.
Stock injectors are only good till around 195-200 whp along with the stock fuel pump.
I have seen stock fuel pumps give up at 195 whp on older eg hatches.
I would recommend a set of 310cc injectors along with a walbro in-tank fuel pump for the 1.8L ls/vtec you are looking to build.

That is not possible on one tune, you would need two separate tunes using dual mapping. One on 93 and one on the higher octane fuel. You would want to use the same exact fuel every time on the higher octane fuel as different fuels have different properties.
