[QUOTE="Stang Lover, post: 16076498, member: 19547"] Yes and they made the comparison in favor to market the 18 manifold. They only ported the 18 manifold and left everything else un-ported and they stopped the pull of the CJ at 7.3K which the CJ is just getting ready to take off at that point. Cobra jet will hold peak power to 8K RPM while others make it for that moment drop off. Have your tuner set it higher. Mine is set at 8.2 I believe just in case I miss a shift. I shift at 7.8-8K with no issues. I would also look into a new tuner since you said the CJ started to drop off at 6900. If you're on facebook join the All Motor Coyotes group. Good people and knowledge in there. [/QUOTE]
