If your truck is studded, which I believe your original post asked for studded tunes, I would go with Matt's SRL+ or the Super Panty Dropper from Truck Source Diesel. I wanted to order tunes from TSD, but they are so overloaded with emails, that it was hard to get a hold of anybody. From what I understand, they arent going to be doing email tunes for new customers anymore. This is because they like to do live tuning, which if you have every done a live tune before, you would understand why.
Like everybody has said above, any tune your going to get from one of these reputable vendors, is going to knock your socks off. Plan on going through your first few tanks a fuel QUICKLY, and finding excuses to go places and drive. :evil
HOOV3R... did you have to rewrite your tune for the FICM? I havent been able to do much research on the tuned FICMs yet.
