2004 6.0- Missing

[rhcdjr]

Help,
I have a 2004 6.0 with minor mods, after market exhaust, cold air intake. When the engine is cold I have noticed a miss, it seems to clear up when warm. I use Cetane Boost on long trips to Tennesse when towing and I change the fuel filters every 10,000 miles. I'm leaning towards injector or pump problems is there any suggestions how to isolate the problem without replacing unnessarrary items.

How many miles? Could be your injectors sticking when they are cold. Do you have any codes? Can you run a cyl contribution test or a buzz test?

The truck has 50k right now, there are no codes. The tests you discribe I have not done before.

you need a snap on scanner or auto enginuity to do the buzz or cyl. contrib tests. run cyl contrib test several times and see which ones come up all the time. If you dont run it several times, you can get false readings sometimes. if you dont have access to either of those scanners, you will have to take to the dealer.

Most of us are running sct, and wouldn't touch anything else.

Why?, my goal is all about helping with towing my tractor up grades and better MPG when towing and empty. So what makes your product work best for me??
