2010+ Mazdaspeed 3, I recommend to monitor your fuel pumps closely

You should be fine with the stock pump on those mods. Nataphen is simply suggesting that if you plan to get a downpipe or anything that adds more power down the road that you save yourself some potential heartache and buy a new HPFP or internals. I am an alpha tester for Cobb and they had to tone back the tune on mine because we were already going beyond what the fuel pump can handle. And that was stage1 with a SRI only

Thanks - I was really only planning on the CS intake and racepipe, and keeping everything else stock in terms of powertrain and ECU.
