The computer in your 99-03 7.3L Powerstroke Diesel equipped vehicle will turn on the light at about 24psi of boost (some calibrations may come on at lower pressures)...a pressure easily attained by today's high performance chips, tuners and modules. At the same time, the computer will reduce fueling (power) in an effort to bring the boost pressure down. This reduced power mode will remain in effect until the PCM sees enough continuous operation without the fault (usually a few minutes of driving), the ignition is cycled or the code that tripped the SES light is cleared electronically.
The Driven Diesel easy to install "Overboost Annihilator" kit will prevent the computer from setting the SES light and defueling the engine FOR AN OVERBOOST CONDITION (the light may still light for other reasons)...maintaining full power at ALL boost levels. This kit is pre-set to show your MAP sensor a maximum of 22-23psi.
**Monitors that read boost from the MAP sensor will stop at the pre-set max of the Overboost Annihilator
This kit works simply by preventing the MAP sensor from seeing more boost than we want by means of a regulator...a mechanical solution to a mechanical problem.
Please be aware that installation of this device DOES NOT GUARANTEE that you will no longer get an SES light at about 24psi of boost. PLEASE SCAN YOUR TRUCK and make sure that you are purchasing this product to cure a P1249 or P0238 code BEFORE ordering. If you still get an SES light after installing this product, please CLEAR YOUR CODES, DRIVE THE TRUCK TO GENERATE A NEW SES LIGHT AND READ THE CODES AGAIN...you are only having an Overboost issue if you are STILL getting a P1249 or P0238 code. It is very common for P1211 "Injection Pressure" codes to happen under heavy throttle about the same time the truck is making it to 24psi of boost...making it seem like an overboost issue.
WARNING: This device is designed to allow boost pressures in excess of those considered "safe" by Ford Motor Company. Operating a stock Ford turbocharger at higher than recommended boost levels can reduce it's service life. Use at own risk.
