Tokyo Motorsports has been tuning Mazda 3 and 6 MPS for several years now. Good gains in power and torque can be achieved with simple bolt on modifications and a tune. The factory drive-by-wire throttle deliberately limits throttle openings on these engines in some gears, limiting power and torque.

Utilising ECUTEK software the power and torque output can be significantly increased without compromising engine reliability.

Tokyo Motorsports offers first class tuning/mapping using a relentlessly accurate, in house, AWD Dynapack chassis dynamometer. This is used to measure engine speed, power, torque and fuel mixtures. Highly specialised software is then employed to adjust the Engine ECU settings (maps).
