Hey Scotty love the show!
I have a 2011 Chevy Silverado 15000 205k miles 5.3 V8 4x4 with vortec that's heavy on the acceleration and nobody can figure it out. Used to have low oil pressure but it's good now.
Things that have been checked or replaced:
Crank shaft sensor, oil pressure sensor, knock sensor, maf sensor, throttle body, k&n air filter, oil filter, catalytic converter/muffler, transmission. I've done the at 205 for the oil but not transmission and have run bottles of Lucas, redline, and royal purple fuel cleaner. Even did the motor flush.
When it gets past 3rd gear everything is fine. Just doesn't pick up well between 1 and 3. Nobody can figure it out. Still throwing off a maf sensor code. Everything we've replaced made it better but still hasn't solved the issue. Only thing left is the fuel pump though I doubt it and the oil pump but it's not overheating. This model doesn't have a stand alone fuel filter as it's built in to the fuel pump.
What do you think?

Check fuel pressure. The built-in fuel filter (usually a fiberglass sock) can clog up just like a replaceable one, so you'll want to check that out as well.
That's my next step probably
What's the MAF code? You want to resolve what's setting the code before looking at anything else
I'm not sure but I can find out
