High horsepower engines need to be fed the proper amount of both fuel and air to keep the engine happy. The need for more air flow can mean the stock MAF sensor can get maxed out. In situations where the engine is making 320 Wheel HP or more, the factoryMAF sensor will become maxed out! This limits the amount of Horsepower your ECU can be tuned for. Perrin has devised away to literally sneak additional airflow around the MAF to increase resolution in timing and fuel maps on your tuned ECU. Combined with the wisdom of a proper tuning guru you can add tremendous horsepower andtorque.

NOTE: Requires aftermarket ECU Tuning.
