You lost bottom end I take it? Did you see an improvement anywhere? Your JR intake may be the culprit. Now that you have headers the engine can breathe easier. Just need to give it more air.
I have an 03 4X4 with the same headers and picked up more mid-range than anything else.
I have K&N (57-1533), FM40, RP, shorties, hollow cat and 32X10X17 Toyo's on chrome steel wheels.

Duane at 3rdstrike can help you.
