• Freeze stock MAP/MAF signal at a set value • Prevent out-of-range sensor values for stock ECU • Ideal for boosted engine applications

The FuelTech MAP Clamper is great for car enthusiasts and mechanics working on boosted engines. When your engine goes into boost, it freezes the stock MAP or MAF signal at a certain value. This stops the sensor from sending values that are too high for the stock ECU. It's a handy tool for making sure your engine runs smoothly under high - pressure situations.
