1UZ suddenly feels very underpowered, but everything seems ok?

[GLOB]

I have a TE72 with a 1UZ with a w58 running on MS2 and EDIS 8 for ignition. It was running fine for a good while and recently it has become very sluggish. It seems generally slow to rev, but otherwise it drives fine. AFR's, ignition timing, mechanical timing, TPS etc all seem to check out fine. I re did the timing belt, made sure that EDIS isn't in limp mode at 10 BTDC and it seems like its putting out a pretty strong spark. Other than that, it used to easily rip loose in 1st gear and now it doesn't get anywhere near that and I can't seem to find any major changes I've made in tunerstudio. Engine runs and idles smooth, nothing seems to show anything is wrong.

Basically, the 1UZ is suddenly slow and nothing seems to show why.

Any ideas or suggestions?

(I also posted in the standalone tuning section)

have you checked with a timing light to make sure the timing is advancing under acceleration?

Yes I did, and it was advancing fine. That was definitely my first assumption. I was kinda bummed to find out that it wasn't that easy of a fix.
