well at first it ran way worse. I had to reset the ECU twice I think for it to calm down and start to perform. One of the other guys on another forum said his actually did run better on the stock filters. I had already changed it so wasnt going to change it back.

how do you reset the ECU?

i thought the ECU would automatically change/compensate and adapt to the new intake system.

at the end of the day the easiet way is to disconnect the neg terminal off your battery and leave it off for 12 hours. The system has electronics that stores a charge so you have to wait for it ti discharge.
Take the neg lead off the battery as in unbolt it and physically remove the cable from the battery. Now take that neg wire you just unbolted from the battery terminal and pull it over and touch it to the pos terminal on the battery. THIS IS NOT SHORTING OUT THE BATTERY !
You are discharging any charge in your system.
Bolt the neg back onto your battery and your all done.
If your not comfortable with this or dont completely understand what I have said please do not attempt this.

A dead short across the battery terminals when they are conected to your electrical system could result in the battery exploding in your face and also blowing a hole thru the ecu main boards so again if your not sure then dont touch.
