Just installed my tuned FICM from Eric. Truck has been sitting for about a week in cold weather (teens at night, 30-40 during the day). The question i have is after the install should the truck be hard to start? The truck is running after 4 long cranks (30sec).
When you get your FICM flashed eric takes out the heat inductive flash and that's why it starts like that. I am pretty sure that's what its called. I put rev x in my truck and it starts a whole lot better so you might wanna try that.
my truck has been cold starting like crap and chugging white smoke for about 30 seconds until warmed up running a tuned FICM. The rest of the day it starts normal though. I am running 15w-40 now, but almost always run 5w-50 sysnthetic. Will be switching soon to see if that helps.
