What valve springs are you running with your setup? This does not ALWAYS happen, but SOMETIMES does - my buddies car was valve floating after 5500 RPMs, and the check engine light would flicker, and had a random cylinder misfire code due to the valve float. He only had high lift rockers so the misfire code was NOT from having a big cam, or something of the sort.

the springs are the patriot golds that came with the heads when i bought them from patriot
it just seems weird to me of how much torque it made yet the hp falls off could it be the stock ls1 intake or injectors but if it is it still wont explain the torque being so high or is this a regular number people get with my set up? im a little confused

Doubt it's the intake - I've had a LS1 intake car and it pulled hard well past 5000 rpms - I'd take it to a true Tuner and not a guy who just works a Dyno - I know you said it was "tuned" but any tuner who walks away okay with a car doing that probably doesn't do much work on LS1's.

In all honesty... u just answered your own question.. Tuner said injectors were at 108% duty cycle.. Id start there. Grab an ls6 and a new set of injectors. Im assuming you have the right length push rods as well.

so could it be the tune it self? i took it to horse power sales in pompano beach fl because they are known for working and building lsx sick vetts paid 500 bucks for the tune what would have to be wrong with the tune to do something like this ?? i need some advice because i really dont have any more cash to get another tune.

I took mine to a LSx guy this week just to see if it was still making the same power it was 3 years ago, right after the first run he pointed out an obvious issue, and once he had it plugged in, found 4 or 5 more issues. He corrected them all the right way instead of trying to band-aid his way through things.
I don't know Jeremy or Horse Power Sales, just offering my opinion from a 3rd party perspective. If he said the injectors were at 108% and you needed to upgrade them and said that was why it was cutting out at 5,000 rpms, then that was probably the answer you should have gone with.
