Sorry if this has been covered, i couldnt find it in this forum.
I have read a bit on other forums but want to see what ausies reckon.

I just got my tbe exhaust (not installed yet) and will need a tune for it. But the warm weather is here now. So if i do it now will i run lean in winter?

What was the weather like when you guys got your tunes?
Do you think its worth worrying about?

Il probably give MMS a ring and see what they say.
Will update then.
