I got the vortech kit on with the 3.6 pully and it runs like it was ment to be on there. I ran into a few things I got questions about though. I dont have a boost guage, but the car doesnt feel like its boosting alot, maybe a 50hp gain. What pully can I go to on the stock internals and be ok. I dont have any detonation problems, but I am still on 19lb injectors. Also, I put autolite 764s in and I noticed a rougher idle, which is normal for a colder plug, but randomly the car sets off a CEL for #1 cly misfire. It doesnt feel like any missing and I know its not, why do you fellas think it is going off? Let me know fellas.

First, why and how are you running 19# injectors? Second, have you gotten any type of tune? Did you upgrade fuel pumps?

Now, I'm not sure why you are misfiring on cylinder #1, but I would say that you are going to have to upgrade injectors and a pump so that you can get adequate fuel supply for the increased amount of air you're forcing into the motor. You also want to get a tune, so you're car will run properly with the new blower. Contact Tim at T&J, he can fix you up. His number can be found on his website: www.modularfordpowerhouse.com

You are getting a #1 Cylinder miss-fire code because you are sucking more air in that cylinder. Sounds funny but I think you may have a leak somewhere in your intake. A crack or bad intake gasket or something along those lines. If it had anything to do with fuel, you would be getting a random miss-fire EEC Code out of all cylinders, and not just one. It's usually because the a/f ratio in the error cylinder is off. The reason I know this is because my wife's van (a 1998 Ford Windstar) was receiving this code, and come to find out I needed to replace the intake rings and gasket. (comes as a kit) After I replaced these, no more check engine. This is just something for you to think about as a possibility if all else fails you !!

I did upgrade my fuel pump to a 190lph and I have the trex inline, but I still am running the injectors. Its very random and wasnt doing it before the charger so I am kinda wondering. I willl fix it for sure.

First thing I'd do is pull #1 spark plug and inspect it. Regap and try again. You also might want to consider installing fuel and boost gauges. A custom dyno tune would insure you are running safe and optimum power.
