Seriously, this does not plug and play. If you order this adapter and complain to me that it's not working on your stock truck there is a 75% restocking fee. 

Now that that's out of the way... 

2003 - 2007 5.9L Cummins High Pressure MAP Adapter V2

 Our MAP sensor adapter is designed for customers who have pushed past the limit of the stock 5.9 Cummins MAP sensor. With this adapter, it will allow your ECU to read and log up to 150psi (or higher by special request.)

BARO - Barometric Air Pressure Sensor
This is the sensor in the air intake, post air filter, pre-turbo on the passenger side of the engine. The Cummins ECU uses a combination of BARO pressure value and MAP sensor value to calculate the actual boost pressure. 

If you have removed your stock BARO sensor, we have a special line of MAP sensors that are read the difference between atmospheric pressure and internal pressure. These sensors will allow you to get accurate boost pressure reading without the stock BARO sensor.

For street-driven vehicles, we recommend 100psi sensors. 150psi sensors should only be used on trucks that will see well above 100psi. The reasoning behind this is as you increase the pressure range you decrease the accuracy of the pressure sensor feeding the ECU. It is far easier to tune 100psi sensors to smoke less at low boost. Stainless sensors are for those who need to have the best of the best. We have been using brass sensors for years with zero issues, however, the stainless sensors are both more reliable in the long run and more accurate. They also cost more than twice a brass sensor and we have yet to have any brass sensors fail.  

Available for trucks with stock BARO:

  • Honeywell 100psi Brass
  • Honeywell 150psi Brass
  • Honeywell 150psi Stainless

Available for trucks without stock BARO:

  • Grays 100psi Brass
  • Grays 150psi Brass
  • Honeywell 100psi Stainless

Not all sensor combinations are possible, if it says "Unavailable" it's not because it is out of stock, its because the pressure sensors don't exist in that exact configuration for a reasonable price. (IE: No BARO 150psi stainless sensors, they are $300+ for just the sensor and no one stocks them.)
