Problems with High RPM

Problems with High RPM
Ok here is what I am dealing with and need some help.
I am running a roush I/C charger and I had the tuned last week but had a few problems. I am seeing the same problem on the street too.
Ok here is what is happening, When the truck was dyno it had probelms in 3rd gear and getting the truck to run over 4000rpm at WOT. It produced 300hp at the rear wheels at that RPM but it was like it hit a brick wall. And if I am running it down the road and roll in the gas it also gains speed but has trouble making 4000 in 3rd. As for the other gears it runs up to the 5000 mark pretty quick without any problems.
What could be the problem?

I know this will sound funny but i don't run my truck hard so i don't know if the roush tune did the same thing or not. But I go back Tuesday to put the roush tune back in to find out if it does it with the tune. Not really sure why I went with the supercharger because I baby the truck but I like knowing it is there if I need it.

It hits the wall around 4000rpm and 80mph in 3rd gear but back off on the throtle and let OD shift in and it keeps climbing pass 100. But at that point I back off the gas.
I am running 35' with a 6 inch lift so 100mph if fast enough. Also I have regeared it to 4.56 to offset the tire size.

Maybe but we could not find it. If you let the truck go into OD it goes pass 100 without any problems.

On another note...If you "baby this truck" and you're not really sure why you went with a supercharger then why not put the truck back on the Roush tune and leave it at that. At least it will be safe. No point in custom tuning unless you are wanting every hp you can get, right? Also be very careful about who you let tune it. Plenty of tuners out there that think & claim they can tune anything because they tune Mustangs and quite frankly they are idiots and dangerous.
