5.7 Hesitation during Slalom hole shot

I just purchased a 2007 X7 (197) with 190 hours and took it out on the water to ski with for the first time last week. When pulling a heavy skier 190+ lbs skier out of the water I noticed about half of the hole shots were weak- say about 85-90% power. Once I would hit about 3200 RPM the engine would open up and be at full power again. The perfect pass was engaged at the time. This happened when the PP was set to use GPS or RPM.

Due to work obligations the boat is in storage for the next 3 weeks, but I'm trying to brainstorm some ideas to attack this problem when I return. So far I've ordered a can of Seafoam to run through the tank to clean up some injectors. I'm also going to fully reset the PP because for some reason I would set the cruise at 34 but it would only pull at 32 mph. 36 would pull 34, etc.

Any other ideas? Could this be a fuel pump problem? Thanks in advance.
