Started out on 75 shot, after I installed tr6 plugs it seemed to kinda have a hickup while idling but drove fine. Is this normal for colder plugs. Also took me forever to get the 91 octane tune down to 24 degrees. My parameters had to be set to like -15 to get to stock. Its slow as hell now on the street, should I put more back im it? Other than that the zex 75 shot felt good. my bottle pressure was at 950 would it be better at 1000?
