I just recently helped my friend who has a Mazda Mx-6, 93 coupe install nitros so he could street race around town against some hot shots. After we installed it we took it for a test drive and every time he shifted the nitros would kick in for a brief moment. Whenever he stops the nitros kicks in full blast an rockets him across the road. We installed it with a perfessionals help and noone know what went wrong. Any one know?
