Acceleration hesitation

Acceleration hesitation
HI all,
I have a 09 JCW Clubbie that has a tune and a few other mods. Recently did the timing chain and cleared super knock codes. Upon acceleration I have an occasional hesitation around 5k rpm. Not all the time but its like if you were to lift off the gas and press the gas a few times in a row. There are no codes right now but I notice the long fuel trim is around -13.
Let me know what you guys think.
Thanks!

Al i can think of is HPFP getting weak or carbon build up. But if those are both fine i would look at the tune. Did you change out plugs and coils, they JCWs tend to need new plugs more often.
