Does your subaru like the cold weather? mine seems to run a little rich when it's colder outside. I also did the coolant line wrap,phenolics, and header wrap recently and i wonder if that change in engine bay temp can affect afrs..

Thanks everyone!

 

Sure does. All engines do (denser air) especially one using forced induction.

 

the colder something is, the more dense. That goes for fuel and air... Since your mods have cooled down the incoming air, the air is more dense (therefore you're getting more).

You need to get tuned, let us know if the problem persists once you meet up with Nick.

 

Not true for all things... such as water (it expands)... sure that is irrelevent to this just wanna correct you...

 

au contraire... The Expansion of Water Upon Freezing

 

thanks for the input, I always wondered what was going on... Question:

I'm probably going to move back to indiana soon, which is 800+ sea level. If i tune here at 65 degrees, can I still use that same tune up north or will i need retuned due to elevation? Is it temp and elevation that affect it?

 

everything affects the tune. dont even think about changing that radio.
