7.3L mid range throttle lag ?

I have a 2001 F350 with the 7.3L in it, I have started noticing mid range throttle lag. up to 1/4 throttle is good power also 3/4 and full throttle has good power no real lag, it's just starting to get going " from a red light" under easy acceleration 2/4s throttle I notice a bad lag in power ?
Anyone seen this and if so help. thanks

May also be not shifting right in mid range, not sure seems like the motor hangs or bogs a bit then will shift later than it should..
This only happens at 2/4s throttle above or below 2/4s throttle everything runs awesome.

No it won't send any codes or at least it didn't on mine, I took mine off and spayed electrical parts cleaner in the crack while working with screwdriver then sprayed wd 40 and worked a little. Has been great for almost a year now. Napa sells them also but not near the quality or price of oem.

Found the problem, it was air in the fuel system from what I resealed the hpop. It fixed itself.
