Hello. Silly question. So finally i have done most of my MODs and purchased my Versatuner, and the gas price sky highe now..
So i have corksport SIR, Catless downpipe NO HPFP yet!! i try to save some on gas but i would like to keep versatune tune on my car as its runs much better then stock. WHAT Version can i run on 91 OCTAN with this mods?

Cheers.

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.

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.
Cheers
