Default Torco or not?

Hi guys,

I'm wondering if running Torco on my EJ20K will have any negative effects? Or even if I will see good results?

My basic concern is the low octane gas I get here in Costa Rica (91 tops) and I want to avoid knocking, specially during track days...

Engine is absolutely stock! Not even more boost or any other change....

Can I use Torco as DD? I've heard Torco damages catalyc converters and O2 sensors...

If only used for track days, would I get good results? What would be the best "formula" of gas/torco?
