Overall very satisfied with the Dynatek FS box. Since adding it to my 2004 Dvx 400, my quad's mid range has a lot more punch. The extra rev range is a definite plus as well. The added torque and improved power have given extra life to my ride!

i purchased this controller for my raptor 700. i have a full exhaust(hmf) and a complete intake kit. before the controller i was experiencing a little delay when i would hit the throttle. nothing major, but enough to notice. now the throttle response is instant!! i couldnt believe it and neither could my boys.. def. the best mod i got. buy it!!!

with a branding like yoshimura you know its not second rate. yosh has sooo much support with this. they can build a custom map for you or can upgrade to O2 sensor tuning limitless this is the BEST controller on market hands down!!!! Now my bike sounds as health as it should. This is magic when paired with full yosh!!!! Amazing
