Default Can someone tell me why i have no power between 4500 and 7000 rpm in first gear?

So when i take off in first. I can feel the pull real strong, then it gets up to 4500 and i dont feel any power, almost like its gonna slow down if i dont shift, I cant hear the engine and the rpms growing but thats about it.
ive got a d16y8 head with a y7 block and a si and ecu
Could it be because that computer thinks it redlining at 5000?
or could it be that i have stock headers with cat-back.
Could it be because my car sometimes idles at 650 and sometimes 500?
Could it be because my cam pulley's "up" sign is at 10 o'clock?
Or could it be that when i was seafoaming the vacuum tubes (brake booster)
i Foulded my spark plugs and need?

Your help is greatly appreciated!!!!!!!

You check the plugs by just pulling one out and looking at it, see what the condition is and might as well check the gap while your at it.
