Whats the best outside temperature to tune with the VE analyzer in tunerstudio. Do i tune it with on a warm day or on a cold day

How well does the megasquirt deal with the temp change?

air density correction should be at 100% when MAT is 70 degrees F. So, tuning around 70F will give the best results.
If your tune goes rich or lean at other temperatures you can use MAT correction to fix this, but it's not always needed.

I think the newer firmwares allow you to actually change the GAIR correction but im not sure.

After you have a good base tune, you have to wait for seasonal changes to finalize things like cold start enrichment. You can get it in the ball park, but it is hard to get that spot on in the summer when "cold" is 50F vs winter when cold is -15F

every firmware has ability to tune the GAIR corrections, thus any ambient temperature is perfectly fine to tune at.
