Default Problem with car at WOT in higher RPMs...

Car is an 01 with TSP Torquer Cam, and full bolt ons.

I was out last night and decided to get on it. I put it in 3rd on the highway and floored it, and the car pulled to upper RPMs, (around or above 5k, usually spin to 6500ish) and then it just seemed to slow its pull down. No weird noises, no codes being thrown... Just seems to lose power.

I am not sure how many miles are on the Valve Springs (PRC dual springs), as I bought the car with the mods it has. I know the clutch is crapping out on it, but if it was clutch slip, I would think it would still rev. Any one have any ideas?

The car has had the same tune on it for a while now... no mods since the tune aside from a throttle body. The car just started doing it.. I slowed down and did another pull shortly after and it did it again... I am hoping its something simple like the valve springs...

Check air/fuel raitios. Definitely a huge possibility. Sounds like the problem to me, also check for knock retard if you can find an autotap. SOund slike it could be a bent pushrod too
