6.4 not runing right after dpf/cat delete

hi, so heres how it goes. 09 6.4 powerstroke pretty much stock except k/n air filter, dpf/cat delete/ and sct 3015r tuner. truck ran awesome with and without tuner before the exhaust mod. however after the dpf/cat delete it runs poorly most days. some random days once a week or so it runs decent. this is all on the race tune. the truck runs fine on street, stock, and tow. thinkin it may run better when it gets warmed up. no longer any rough idle after i changed out an egt sensor and sounds fine. when driving there is really slow throttle response, low boost, and low power. im just confused because it ran awesome like 2 days ago and now it runs like crap after i dpf delete. theres no codes either. any help appreciated thanks.

Everything plugged in? I reverted to stock exhaust for smog and left a connecter unplugged. End result was similar to yours, low boost, no high end power, CEL, sluggish response. Just a thought, but check the connections if they are still used....
