For some reason after i put on my Invidia G200 exhaust and injen cai when i rev my engine the needle doesnt goes up as fast as it use to(or it doesnt repsonse as fast), but i really like the sound of the intake though, so do i lose power or there is just no gain for me? i didnt pay attention hows the rev goes when i only got exhaust itself, any1 know wats the problem? i also have the 5/16 MD spacer now, my engine is VQ35DE

 

1st, trash the injen cai. Its gonna cause trouble when it rains. Try a full ECU reset.

 

how do i do a full ecu reset? or you saying i should send my ecu to like technosquare to get reflash?

 

Disconnect your battery overnight and it will reset.

 

do i really have to disconnect itovernight or 10-15mins is good? And all i need to do is disconnect the battery? do i have to do something else?

 

I've personally have never heard of disconnecting the batt for 24hrs to reset the ECU. From what I have always been taught was to just disconnect the batt and “pump” on the brake pedal for a extended period of time (2-3 min) to discharge all the capacitors in the car. Discharging the caps in the car would dissipate all the latent charges stored throughout the various circuits in the vehicle.

 

Probably. You should put that car back the way that it was.
