Ok. So have you run any datalogs?
When you say "low power", is that seen when on the dyno, or is this a "butt dyno" test?
You say the FP is 60# @ the rail. Is it still in that area when you run it under high load? [FP gauge on the W/S, and drive it.]
If you have the required FP and the engine is running with no load,[very low flow required], does not mean the pump/system is keeping up w/ hi demand.

i actually drove the car for a bout 20 min and it just went back to normal out of no where...but then once i turned it off and got on it again...it started acting up again
im at the point where i have no idea where to look next
i already checked and cleaned injectors as well...
i checked many possible causes and nothing
