any insight?
pertinent mods: muffler delete and panel filter.

Thats going to happen on high ethanol content (over 75 %) in cold weather.
you can help by either adding 4 litres (think thats a gallon) of petrol to a full tank of E85
or modifying the injector pulse widths (IPW) to add more fuel at startup
see tune links below in signiture
or here

or do both ie increase IPW and add some straight petrol, just keep the E% over E 60
