Its been posted before somwhere but as long as we are talking about the canned tunes the "93" really means 91+ . So you will be fine.

You probably can, but you may need to retard the spark some (I'd guess maybe 1.0 degrees) because you're probably burning a mix that's actually 90 octane. However, it probably won't matter much. If the knock sensors detect "ping", the spark will be automatically retarded - a lot, and that will prevent damage. But retarding the spark could actually give you better performance right now.

Please update your user cp with your hex and serial number.
Is it cold where you live?
The other thing is it may be time to clean the TB and MAF sensor also.
