AMS Performance ALPHA 4 Bar ALPHA MAP Sensor for Nissan R35 GT-R


AMS Sets the Standard for Reliable Tuning

The Alpha MAP Sensor gives you precise boost control beyond 24 psi. It’s plug and play. It builds on the success of the Alpha MAF Sensor Upgrade, which solved drivability issues for high horsepower GT-Rs. When we pushed the R35 harder, the stock MAP sensor couldn’t keep up. Boost control got sloppy at higher levels, so we built something stronger.

Why the Stock MAP Sensor Falls Short

  • The factory sensor tops out at 24 psi.
    • After that, boost control is gone.
    • The car runs whatever boost the conditions allow.
    • You can’t log or see what’s happening past that point.
    • There’s no real safety margin.

A Better, Safer Way to Control Boost

We designed a 4-bar sensor that lets you control boost accurately up to 44 psi. That gives your tuner clean data to work with and makes your setup safer at higher power levels. It’s simple, reliable, and proven on the dyno.

Easy Install, No Guesswork

  • Plug directly into the factory harness.
    • No cutting or splicing.
    • Works with the stock ECU or any aftermarket system.
    • Comes with calibration parameters and tuning tips.

This is a clean upgrade that keeps your GT-R running strong and predictable when the boost goes up.
