Ficm reprogramming ?

[Farmer11]

I got the gryphon in the mail yesterday to reprogram the ficm. I put the 03-04 IH setting on first. Went out this morning to start it, at about 50* and it coughed over and was shaking and knocking terribly bad. Let it run for a minute or two and it didnt settle out. Not good since up here in wisconsin it gets alot colder than 50. So i shut the truck off, reprogrammed it to 05-07 IH and started her up. Ran like it usually does and i noticed the strategy is only a couple digits differen than the last one i had. I have an 03, and i would like to gain back the power and mileage that it had before reflash. My question is, why does it run rough with the 03-04, and can i get like a custom hybrid type? The truck is an absolute dog until it gets up to 185* Like i can hardly get over 25 mph until it is atleast over 110*

Thanks!!
