Installed an MS3 basic earlier this year, which is my first aftermarket ECU/tuning adventure, so didn't expect my street tune to put up these kinds of numbers. Working from base tune I did a whole lot of research and pulls loaded in to virtual dyno to arrive at my target AFR's. I'm guessing most of the power is coming from ECU + intake following the SuperMiata formula and I'm sure there's still more on tap. RacingBeat header and proper tuning on 93e10 could yield what, another 3-5whp potentially? I'm running a NASA pre-approved reclass for 127hp, so this panned out nicely Best run was right at 127whp before correction.
