Bigger Injectors now Horrible throttle hang

Well I recently installed a set of 50 percent over injectors in my half ton and now I have an issue if you are on the brakes spooling up and let off it continues to fuel at around 1300-1500 rpm for a few seconds then comes down to idle. Note, it DOES NOT have this issue whatsoever on a stock tune. If I select any of my tunes it does it. I tapered off rail pressure on the end and it still does it. Data log is showing it's commanding around 11k psi of rail press and it's jumpy also between 700-1300us off throttle. Any ideas on what to change? I'm stumped.
