OCR - Overboost Code Regulator for Ford 7.3L 99-03

The purpose of the OCR is to regulate the presence of an "overboost code" that sets the Service Engine Soon light and stop the PCM from defueling at 23 psi of boost.  We are the first to utilize a pre-set custom regulator that will allow your MAP Sensor to see up to 22psi before holding it there.  With the use of a pre-set regulator it doesn't allow there to be human error when setting it or to accidently be adjusted out of the correct setting.  By using this highly accurate regulator your performance will not be hampered or degraded.  You can perform this same mod your self with a compressor regulator from a hardware store, but from experience we have learned that these models can be extemely inaccurate at low psi levels.  Because of the inaccuracy and inability to hold the pressure at the same psi you end up adjusting it down there by losing performance. Our OCR was made to prevent overboost, but it doesn't not enhance performance, it allows the computer to perform past what would normally be an overboost condition. If you aren't building over 23+ and experiencing defueling then this product isn't what you are looking for.

To make this a true bolt on product, and not just a cheaper bent hanger, we include a plasma cut, anodized custom bracket that moves your MAP sensor and allows for a clean looking install.

Fitment: 99-03 F250-F550 7.3L ; 2000-2003 Excursion 7.3L

  1. Should have come with new clamps and loom. 3 Star Review

    Posted by on Apr 16th 2018

    I've purchased a lot of things from riffraff and have been more than satisfied with them. Every kit has come with everything needed for installation except this one. It would have been such an easy thing to add new hose clamps and wire loom to protect the hoses. The existing clamps were too big for the new hose, so I ended up with a boost leak. I would have gladly paid a couple dollars more to keep from making a parts store run.

  2. Needed if chipped. 5 Star Review

    Posted by on Apr 13th 2018

    What a difference it made. Any chip should be sold with it also.

  3. 5star rated products 5 Star Review

    Posted by on Apr 5th 2018

    How can I say this, I am not mechanically inclined at all, but installed this myself in no time at all.
    Works flawlessly with no more check engine light, highly recommended!

  4. Looks like it was factory 5 Star Review

    Posted by on Mar 21st 2018

    Installed this on a customers truck, it looks and functions great, this is the only boost fooler I will be installing from now on.

  5. Wonderful 5 Star Review

    Posted by on Mar 13th 2018

    It was easy to install and I throw no more boost codes

  6. Won't regret it of you are getting ses light from over boosting. 5 Star Review

    Posted by on Mar 12th 2018

    This thing looks and works awesome. Very happy with my purchase as always from riffraff

  7. FIXED SES light when over 20psi boost 5 Star Review

    Posted by on Mar 6th 2018

    After installing a TS 6 position chip the SES light would come on every time the boost went pass 20 psi. The light would go off about 15 seconds when the boost dropped below 20 psi. This easy to install item stopped the SES light form popping on every now and then. Item looks nice and clean when installed on the truck.

  8. GETS RID OF SES LIGHT! 5 Star Review

    Posted by on Jan 30th 2018

    Works awesome and got rid of the annoying SES light in the dash! Easy to install. Looks right at home in the engine bay too, great RIFFRAFF item! Thanks!

  9. High quality, Works Great!! 5 Star Review

    Posted by on Jan 2nd 2018

    After doing my 38r and cranking the wastegate shut, I soon learned what the overboost code was all about. It got very annoying, luckily I found this OCR, and it works amazing! Took 5 mins to install, and works as it should.

  10. Very Nice Product for Finished Appearance! 5 Star Review

    Posted by on Dec 22nd 2017

    This is an exceptionally nice machined plate with fool proof pressure regulator for fooling the MAP sensor. It is very professional looking and installs perfectly.

    I did change the supplied hoses to the correct reinforced/braided hoses equal to the OEM installation. I did not feel that a soft rubber vacuum style hose was adequate given the potential boost pressures seen by these engines.
