If you went to the track earlier this year, then the weather was probably cooler which would make a difference on your times.
Despite the weather, your truck did pick up horsepower. Look at the trap speeds. The additional power probably made it more difficult to get good traction as shown by your 60ft time.
I ran my best ET ever at HRP the weekend the track repopened after winter break.

I have OBX LTs.
It just seems like for people with stock cam trucks, these long tubes have too big of primarys for stock cam fairly stock engines. Although I didnt notice any power loss down low with my OBXs I dint notice anything up higher either. But then again I havent dynoed or went to the track to verify, but as far as I can tell it didnt do anything.

I'd say your buttdyno is just off. You should have had a very nice midrange-upper rpm jump in power.
Oh and i have a stock cam truck with pacesetters and e-cutout. Truck goes faster with the cutout open and has ran a 13.7@99 a handful of times now.
