Hey I think the dyno day would be great. I would like to see if there is any variation in small mods that may take place over the winter

I doubt I will need any retuning though.....As for the discussion question, I dont drive mine in the winter, and only in the rain if I get caught out in it. I have the silver bullet v6 for a DD lol. Main problem is the drag radials suck in rain and I could only imagine snow and trying to get up my driveway haha.
