Bad MAP sensor?

Hello everybody! Before I start, the car is a 1.4T, 6-speed manual with DRP CAI, Madness ECU, Tork Intercooler Pipes, and DRP Race Dump. The waste gate is set at 4.5 mm. 11,600 miles.
My two CEL codes are P0107 and P0237, which, according to Autozone, is MAP sensor and MAP sensor too low too long, respectively.
Yesterday I was using my vehicle for work. It was hot outside and I drove it 150 miles, evenly split between highway and city. After awhile, it would seem to lose the power that would come in around 2500 with the turbo. I figured it was just due to the heat. It was running around 205, higher than my usual 185. However, when I would take it on the highway, the first pull or two through the gears felt like normal power. After those couple runs, it was back to feeling weak.
Keep in mind, the only thing odd I'm feeling is the lack of the surge of power from the turbo. It still runs and idles as normal, and I can still hear the turbo (which might be quieter, or might just be me thinking it's quieter.)
Today, I start it and my CEL is on. It drives no differently than it did yesterday. However, even after it had a night to cool, the loss of power was still there. After I got the light addresses (codes above), I tightened all of the clamps on my intercooler pipes. I also unhooked the battery while I disconnected the ECU. I started it without the aftermarket ECU, and the CEL was off. It drove marginally better. I then reconnected the ECU, and the CEL was still off, but the car isn't 100%, assuming my butt dyno is accurate
I would really appreciate any input! It's odd that this seemed to happen so suddenly. Thank you!

Also, it idles slightly louder than normal, but certainly not rougher.
