Re: tune selection
You should not run a caless DP with no fuel pump internals especially on gen2/BL mazdaspeed3/3mps.
Other than that any 91OCT/95RON tune will be pretty much equal from a safety standpoint. But because no HPFP internals I'd say to stay far far away from any high load tune.

Re: tune selection
Thank you very much your reply. 
I haven't been running it for long time , and it said stock hpfp would be ok. I have ordered the hpfp internal already.
