Alpha Performance R35 GTR 4 BAR MAP Sensor Upgrade

The Alpha MAP Sensor is a solid, plug and play solution for precise boost control over 24 psi. Alpha R35 GT-R MAP Sensor Upgrade AMS Leads The Way For Solid Tuning Solutions The Alpha MAP Sensor is a solid, plug and play solution for precise boost control over 24 psi. Following the success of the Alpha MAF Sensor Upgrade, the first on the market to solve drivability problems for high hp GTR’s, we quickly found it necessary to upgrade the MAP sensor for the R35 GTR. We noted that higher boost levels created inaccurate boost control with the R35 GT-R and we needed a bullet proof solution. What’s The Problem With The Factory MAP Sensor? The factory MAP sensor only reads to 24 psi reliably which leaves very little room to have a working boost cut in case of an over-boost situation. The factory boost control is also pressure based so after 24 psi there is no longer any ‘control’. The boost will run whatever it wants to in relation to air temperature and density for that day. There is also n
