Yea that was problem my friend if the car was a Red Honda Hatchback. He was just running a NOS fully ajustible kit for a eclipse i think. I think he just miss shifted and that took care of his cylinder pretty good. He has the car runnin again but at the expense of a new SiR motor. Unfortunaly I hope that Zex is a little safer because that was im plannin on goin with at the 55 shot.
