I had the same problem. Even in the summer, cold starts were terrible, I got the reflash which helped alot. Now that its cold its starting hard again. There is a new product out called Rev-x. It is supposed to cure injector stiction(sp?) in 6.0s, reason for hard cold starts. It is similar to HSS mentioned above but Rev-x has worked for some when HSS did nothing. I ordered my Rev-x online and got it in yesterday. I will change my oil and add it this weekend and we'll see if it helps.
