Pulling timing on winter gas?

[Chriskozl]

Does anyone have this issue? No issues during the summer, soon as it came round octoberish I started seeing more negative corrections.

Just a guess, but it probably has something to do with winter blend gasoline, which has higher volatility due to additives like butane.

What he said! Winter gas is pretty shitty most of the time.

A little bit of torco will fix it. I use it since AZ gas sucks.

Minus the changes in fuel, does the frigid, dense air have any impact on timings ?

In a positive way, not negative.
