My old thread died out.

I drove around for about 800 miles on break in, after awhile, my car started to lose power, my revs are slower, I"m running rich, my exhaust tone is lower.
I have no codes, no dimming lights, everything is normal except the power loss.
it's too the point where I can't drive it. it's as if the motor has went to slow motion.

example (lame or not, best I can do) it's like something is holding the motor back, or like a 100 lb flywheel

Idle is perfect, motor sounds very healthy.

here's what I've checked/tried, TPS, MAP, different ECU, different dizzy, different wire harness, different resistor pack. timing is all good, just put the head back on and double checked everything, all grounds are there. timing is good.

any help is appreciated. thanks
