I have two tunes that I found here on the forum in the dump for unsupported tunes.

This one runs really well, but kicks a code for electric fans even withthe MIL enablers disabled .

2000_S10_LN2.tun

This one gave me some troubles with how it ran and it kicked codes for knock sensor circuit.

2000s10 flex fuel 2.2stock.tun

Good luck with them.
