f-450 loss of power at wot pulling

Hey everybody been looking around and wow ya'll got a cool thing going here, lots of info. Anyway i have a couple questions about my early 99 f-450. first off its all stock except for a banks torque converter, trans command, and a k@n air filter. I just cut off my muffler and gutted my cat so i can install 5 inch stacks and since then when i'm pulling a load up over bridges or in the throttle more than a few seconds it starts sputtering like its losing fuel. it sometimes did his before but not this bad and the check engine light would quickly blink. My truck weighs 12,000 lbs and the trailer weighs 7500 empty and normally weighs 15-20,000 loaded. Also since i cut it all out the trans shifts sloppy. The fuel fiter is only a couple hundred miles old it looked good when i drained the bowl and checked it this morning. air filter was just cleaded. Any help would be great.

Also I plan on getting some gauges and a Banks exhaust brake soon. I have been looking into Banks Stinger system for some more power but i've heard alot on here about dp tuner and tony wildman. What are the pros and cons of them vs the other or one better, do they do anything for the trans. I'm not interested in racing just staight up pulling power, my truck never see's a day less than 20,000lbs gcw. Thanks alot
