I learned this while talking to a guy from K&N about the proper way to install the intake (not destroy my MAF) He stated to disconnect the battery and leave it off for an hour to let the ecu lose all power and reset itself when power was brought back. This was because if u install the intake and have the additional air going to the MAF without resetting it will think something is wrong and thats where the issue is. Instead now it relearns and thinks the extra air is normal

Not entirely right. Yes, in order to reset the ECU/DME you need disconnect the battery and leave it disconnected for some time. This has nothing to do with the radio. The codes for the stereo are stored in the DME and as long as you are using the same stereo that came with the car, you will not have to enter any codes. There are no codes for the ECU...again as long as it is the same DME that came with the car. If you change ECU, you will have to use a PST2 or PIWIS to reprogram it to mate with the car.

I think im a little confused by that but I have had to enter my code before because i disconnected the battery and let it die and reset the ecu. I didnt remove anything in the system....
