    Since it has gotten colder, it seems my FiST is really rough when starting, not like it doesnt wanna start just that it is very violent sounding/feeling when starting. I do have a Cobb RMM installed but idk it just feels rough.

    Anyone else experience this?

    Sounds like this is another con for the Cobb RMM, with it being colder out I could see the material that Cobb uses in the RMM be more brittle and stiff causing the vibrations to transfer into the steering wheel. I myself have the stock RMM and through out winter of various cold temperatures would have to say the starting has been normal or no different feeling than summer months.

    Define Colder ? I ran last winter with the 2J racing hard mount and when it was -20 it seemed a lil harder running while in warm up but as I have since gone back to stock for various reasons its is fine though with this cold snap of near Zero weather it does take a smidge longer to start and idle up to smooth summer like running.

    Balmy. Nothing is happy at -30C. I spent a winter 2hrs north of Ft. Nelson, -56c was the coldest it got. I'm glad fuel was free... I'm thinking that the stiff bushings in the COBB engine mount are likely going to increase nvh drastically in winter temps.
