2012 DL1000 slight throttle hesitation between 2-3k RPM - TBS Time?

Before I start tearing everything apart I figured I'd ask for the opinions of folks in this forum. (and before trying a shop)

I've noticed that my 2012 dl1000, 13k miles, has a slight power loss on acceleration between 2k-3k rpm. It's great below that and the power comes right back after leaving that range. Has anyone else seen this before?

Bike History: When I bought the bike used 4 years ago, I reverted back to stock by removing an aftermarket in-line ECU tuning module and swapping back to stock exhaust.

Some thoughts of what I've considered it to be / needs

• TBS (not done since I've owned the bike)
• Dirty injectors... but it feels weird this would only manifest between 2-3k rpm and idles fine
• Spark Plugs - Which I just ordered a new set to replace just in case.
• I did an inspection of the throttle body boots and I don't think there is a leak.
• Air filter, but it is newish and clean

I've got to do a bit of a spring cleaning and over a weekend I want to do:

• New brake pads
• Clean the fuel sensor contacts - It's been reading a bit high on gas level.
• New Spark Plugs - It's still on the originals and they were cheap enough to be "why not"
