4.7v Diode mod?

[Dallas4x4]

Anyone know anything about this mod???

Ive been told that it's a type of Boost Fooler Mod. It doesn't allow the MAP sensor to go past 4.7 volts. So it will not DE-FUEL when the truck goes past 20lbs of boost.

Youre pretty much right. here is a thread with tons of input on it and some pictures.

Did the 4.7 diode boost fooler

I think my truck might have it because it has never defuled and I can hit over 35lbs any time I want. I dont know why someone would do it to my truck though since it had no other mods when I bought it. It also has never fallen on its face since I have owned it. Its just a weird truck!

Anyone know if they work for OBS trucks???

It doesnt work on OBS they work on a hertz signal for MAP signal not a voltage signal like on a SD.

You might as well get an air compressor regulator from Home depot and put it inline to your MAP sensor. Have it regulated to 20psi and your good. So you know most OBS' dont De-fuel but some have been known to do so.
