05 and 07 were leased, 2008 is a purchase. Just for the record, a friend of mine has an 05 and performed the processor upgrade at Livernois, and what a difference! His shift points are much better,crisper and NO rev limiter. After the tune he gained 34 horsepower at RR whls. (not bad for a bone stock 5.4), not sure on torque, I'd have to have him dig out his paperwork and see what the improvement was there also. Although I did want to give him a run for his money with my 07 for giggles, I never got around to it....Maybe with the 08. I know it is a truck and not built for drag racing, but common it IS a guy thing.

I have an 08 SC with the 5.4 and I have the following: AF1 3.5, SCT X3 tuner, and had the truck dyno tuned by Troyer Performance. During the tuning I was given lots of info on the Ford trucks. Most of them dyno around 200-208 hp. But the programming on the trucks vary widely so how they get there and "feel" are very different. I know in stock form my 08 was light years better than my son's o4. The peak was very close but between the peaks was a hugh difference. I think this is where Ford has made the improvements. OH, my mods and tune netted 44 rwhp but it sure "feels" like more. So I wouldn't worry to much about HP peaks as stated the tq on the trucks gets it done.

awesome gains! Is that with stock exhaust or do you have aftermarket you didnt list?

I now have the Roush (duel out the rear) they had them "on sale" after my dyno tune so I am not sure if I picked up any more power or not but it does sond good. I am also now getting 16.7-16.8 mpg in town and 18 - 19 mpg on the highway!

I have the AFE Stage 2 CAI and 3 inch Magnaflow SI/SO cat back exhaust. My next mod is the SCT tuner for sure!
