compressor surge

It depends on the serial number of the Neo. Initially there was a linearity flaw surrounding the airflow corrections. Things become very erratic with the Neo's output and can cause major damage. If the last four digits of your serial number are below 13800 and there is no Karmen compatibility sticker on the back of the unit the unit contains the programming bug.

If you have one of the problematic units, you should remove the Neo and reconnect the MAS wire at pinout #90. Keep in mind, that if you are running larger injectors, you'll need to swap back to stock until you get the Neo fixed. Let me know if you need a copy of the form you have to send back with the Neo.
