Scanner reading questions

I recieved a new Actron CP9150 over the weekend and put it to the test. I have been having some driveability issues. I did all the normal test before I got the scanner and couldn't find anythign wrong. Car seems to lack power, hesitate off throttle if you go WOT and I thought it was running lean but who knows. I got some readings I was hoping you could help me with.

BLMS showed 124-130 at idle and I found out my Air/fuel ratio guage is more off than I thought

The CTS reading was 30* higher than the actual temperature outside and once the car warmed up it was 50* higher. Car running at 180* and CTS showing 230*

My TPS also had some odd readings. When I back probed it it was in spec with a smooth transition. The scanner shows .57 at idle and at WOT it will go no higher than 1.41.

What is ESC count for? I know what the ESC does but not sure what the reading is for.

So I am thinking I need a new CTS and TPS, what do you guys think?
Thanks in advance.
