This product is only intended for very high horsepower builds. It will lower your MAF frequency to 82% of the original value. This allows you to work around the 11,500 hz limit in the 3800 PCM. So lets say you are maxing your stock or LQ4 MAF, this will drop the frequency sent to the PCM so you are in a lower frequency in the MAF chart. However you must modify your PCM file to compensate for this. For starters, when this is installed, you will want to multiply your MAF chart by 1.45.
- 5 to 5 wire this is for series III cars with stock MAF sensors.
