Hey guys, I have a 2008.5 metro gray speed 3 with some mods, but I just bought a 2010 pearl white mazda 3 (s sport 2.5L) as a daily driver. I am leasing it so i cant really do much too it at all, but I was just wondering if there is any tuner's or chips for the mazda 3 2.5L engine. I really just want it for the upgraded gas mileage, because i drive it at least 75 miles a day and currently with my mods on the speed, my speed 3 is getting better gas mileage than the regular 3.

So once again:
1. Is there any tuner's or chips for the 2010 2.5L engine?
2. Where is a good site to find aftermarket parts for the 2010 models?

(for my speed 3 i use StreetUnit.com - Premier MAZDA/MAZDASPEED SPECIALISTS but they don't have parts for the regular 3)

Sounds a lot like what I'm driving now. Nice NA 6-spd hatchback. Anyway, congrats.

Re: engine tuning the mz3 2.5l NA: It's a relatively new engine still, there there's not a lot of options out there for ECU reflashing, but one tuner in Texas, Dynotronics, claim they can reflash for the 2.5l MZ3 engine if you mail them the ECU, I think they've been asking about $500. I think they were claiming a 20hp increase over OEM, but I've not seen it independently verified. You can read what I've read here: mz3 forums, 2010 2.5 mazda 3 ECU cracked!
