have you checked if your butt-dyno is properly calibrated? Sounds a little off...

you can reset the ecu by unplugging the battery for a few min.
You can also reset the NVRAM by doing the 20 brake pedal procedure (search for it).

i reset ECU today, and the power is back, but the new problem is the idle bacome unstable when braking, up and down between 1000-500 rpm, i do some search, i think on one has the same problem with mine.

your idle is unstable due to resetting the ecu. The fuel trims will need to be relearned, and this will take about 4-6 drive cycles

your searching needs to improve...

How long were you running your car with the intake and before changing out the exhaust?

Did you check the exhaust for obstructions before the install?
