Ok here's my problem. Bought a stock hemi ram and in the first week did a 6 " lift, 37" tires, magnaflow exhaust, k&n air filter and Bully got gt programmer. Now after doing that all the same week I have a terrible miss in the mid range when I lug the truck up a hill. If I get on it and kick it down it goes away. It's pretty bad miss......I turned off my MAF feature in my Bully dog so it always runs on 8 cyl. Don't want to start tearing stuff off. Checked intake for leaks? Put Bully dog on stock program. Any one have any miss issues with magnaflow exhausts??

I doubt it is your exhaust, do you have any way to data log?

Check your spark plugs. Under load they can miss if they are going bad

Agree with above. Go back to stock tune.

Think it might be my Bully dog? Runs worse the higher I go up in performance. Stock misses slightly here and there. Regular misses more and performance it misses a lot more. Still have that slight lugging in stock though? I have premium gas in it. Thought maybe that was problem? I have 40,000 on my truck. Maybe I will check the plugs? Not sure how to data log? I'll look into that tomorrow with Bully dog programs. Maybe it will tell me something?? Truck ran awesome before? Don't get it? It should run awesome with those upgrades I thought? Don't get it.....

Someone will correct me if I'm wrong, but I think the service recommendation for plugs in a 2013 Hemi is 30,000 miles and that changed to 100,000 starting in the 2014 RAM's. So if I'm right that may be the best place to start.

I'm going to try that this weekend. I hope that's it. What spark plugs you guys recommend without going ridiculous? Also how about oil/filter brand?? Full synthetic?

I'm going to try to do an "uninstall program" n my Bully dog too. Thinking that you guys might be on to something about the plugs because higher mode I put it in on my Bully dog the worse it gets. Soooo every level that gives it more spark makes the problem worse....
