TKSR HELP New to this

I need some help with the tuning and I am new to this. I have a 2009 GMC Sierra 1500 (4.8L). I have done Air Raid CAI, MagnaFlow muffler with resonator removed, Power Aid Throttle Body Spacer and of course the Diablo Trinity Programmer.

I have installed the 87 octane tune and have adjusted my tire size. I have also done a few logs (before and after) and have adjusted my LTFTs with the DSLogRedux program. I have attached the file after the tune was performed. My average LTFT Bank 1 is -1.44327% and LTFT Bank 2 is -1.48481%. I have also done a WOTAFR tune as well. It told me to adjust the low RPM range 6%, Mid was good and High RPM range -3%.

I have made all the adjustments now and am getting ready to do a highway run. Is it normal to get some TKSR under wide open throttle? Also my other main questions is at the moment all this tuning was done at 8 Dec C. Here we get temps of like -30 Deg C in the winter. Would I have to redo the whole procedure again or just do minor tweaks and if so, what kind of tweaks?

I have attached my WOT data below after tuning. I would like someones opinion if it looks good or not?

I have now done a steady highway drive for about 20 minutes. After adjusting my WOT PE ranges and doing the highway drive I have noticed that my LTFT Bank 1 is now -0.15889% and my LTFT Bank 2 is now 0.
12998%. These values have changed from the previous values after performing the WOT PE adjustments. Are these values ok or should i do more triming?

the values are good, if your intake air temp was 90+ degrees.....

if your intake air temp was lower, like in the 60's, 70's, etc.. then your average ltft's should be a little more positive...

I checked the intake air temp and it was around 13 Deg C. Also, if i adjust the injector slope, would i have to re-do the WOT PE adjustments or can I adjust the slope and thats it. If I need to go a little positive, how much do you suggest. I live in canada and at the moment the day highs are 10 and the lows are -5 deg C. Should I also be adjusting the slope based on the seasons? I attached the CSV file below

Thanks
