Most modern factory boost controllers tend to build boost conservatively and then taper it away noticeably toward redline. However, a GFB Atomic Boost Controller not only allows quick and easy boost level adjustment but also can reduce the boost threshold and maintain a rock-steady upper limit. Put Simply - more power, earlier and longer! While increasing the boost is a very easy way of extracting power, it should be done sensibly and with a little appreciation of the mechanical limits of the engine. Therefore it is important to use a boost gauge and make small increments. Raising boost levels will increase the amount of mechanical and thermal stress on all engine components, so check with your mechanic or tuner before making any changes - In some instances more boost does not necesarily mean more power so contact info@mrtperformance.com.aufor the best advise.
