2012 Tundra hits limiter in tow mode WOT after flash

so i bought some credits the other night and tuned my 2012 Tundra, I only adjusted the normal mode(non tow) shift points to hold the gears longer, as well as making the throttle more aggressive in tow mode. The truck now will not shift 3-4 or 4-5 in tow mode at WOT without me letting off. i have gone through all the shift points and convert apply and release but the only thing i can see is the
trans-hot-tow converter table keeps the converter locked but i don't know why it would be using those tables. any help appreciated.

so by extending the shift, i assume you raised the shift mph/rpm. you likely raised it too high, you cannot raise them to maximum rpm, there has to be time before the rev limiter to allow for it to shift

i did not raise any of the shift points, the only thing i did was lower the downshift rpm so it has to rev down further before downshifting because i didn't like that it shifted around so much if i got on the throttle

Your adjustments were made with the understanding the RPM in those tables is output shaft RPM, not engine RPM?

no, I assumed it would be input(engine) rpm not trans rpm, also converter output or trans(drivshaft) output?

for the shift points or the converter lock/unlock or both?

Output shaft RPM for both

In the future, attaching your tune and a log helps, much easier for everyone to see what's going on

Here's a quick and dirty spreadsheet to convert to more usable units (engine RPM, vehicle speed) - yellow cells are inputs, green cells are calculated Attachment 96044
