My story


I’ve been tuning engines for over 5 years, starting with my first car, a naturally aspirated Miata that I built and turbocharged myself. That project taught me how powerful tuning can be when you understand every piece of the engine. From building the block to custom fabricating the turbo system, I dove deep into engine building and tuning fundamentals using a Megasquirt ECU.


Since then, I’ve heavily focused on continuing my knowledge on more advanced theory behind how engines work and what factors play into delivering the best final result.


I focus on drivability just as much as power. testing things like idle control, cold start, throttle response, and of course the fun stuff too: rolling anti-lag, boost by gear, flex fuel tuning, and advanced engine safeties to ensure the best result, that lasts

Whether you're running a simple bolt-on setup or building a fully forged engine on ethanol, I bring precision, real-world testing, and custom solutions to every tune.

Your car deserves more than a cookie-cutter map. Let’s get it dialed in.
