...I have a tunning session with Steve Kan this Saturday and out of no where 44* for Saturday. That is pretty cold to Texans...LOL!

Is this bad or good?

TIA

It's better....you run slightly leaner in cold weather. Your water temps will be normal, so the only thing that will be different than "normal", is that your air temps may be cooler. However, sitting still on a dyno may offset that difference anyway.

I agree with ryberg. Car will run much better in cooler weather. Air is more dense

I think its good to tune in colder weather but not too cold, Make sure your air temp corrections are set good

Cool. I knew my supercharged mustang ran faster in cool weather but want to be sure. Look forward to visit Gotham Racing anyway. Alex is a nice person to talk to.
