P2135 P0642

So i have a 2017 f150 supercharged..
i drove it for 7 months not a single issue. then last week when it got hot it started to act up when the weather was 30C.

It threw the good old wrench with a p0642 P2135.

so i repleaced the Gt500 TB with a new one.. and also went and replaced the jumper harness from the OEM TB connector to the GT500 tb for s/c applications.

worked fine for 5 days till yesterday was about 30C and it happened again..
any thoughts?

Could be tuning, problem with the TPS config and sensor slopes.
