ATP Boost Cut Defender for Mazdaspeed3 07-13


ATP Mazdaspeed3/6 Boost Cut Killer


The ATP boost cut killer, aka “boost cut defender” when coupled with an aftermarket boost controller, will allow you to run elevated boost levels in your Mazdaspeed3 without hitting the dreaded factory boost cut. This simple device is installed in-line before your factory MAP sensor and allows you to run more boost without the computer electronically reducing boost. Great for stock turbos running aftermarket manual or electronic boost controllers as well as big aftermarket turbo upgrades. As this product will completely delete your ECU’s ability to recognize overboost, it is very important that this device is only used in conjunction with a quality boost controller and boost gauge and carefully set and monitored to avoid potentially damaging overboost conditions. We strongly recommend that you monitor A/F ratios as well when using a boost controller on the Mazdaspeed3.

Note:This part will almost completely eliminate your factory ECU from protecting your engine from overboost. Careful monitoring of boost levels is critical when using this product. Purchase at your own risk.
