Fordtechnician Posted February 13, 2007 Share Posted February 13, 2007 I have one coming in today, it supposedly has 2 ebp codes. They claim while going down a mountain and on the brakes the turbo will spool up. (This makes the truck go even faster). They also see increased boost psi on the gauge! What am I going to look for. I never heard of something like this. Am I going to find it is chipped or has a jake brake? Quote Link to comment Share on other sites More sharing options...
Fordtechnician Posted February 13, 2007 Author Share Posted February 13, 2007 No codes present. It IS chipped with a banks system. It also has a oversized intercooler, ductwork etc. Can't find a jakebrake. Would just love if a fse walked in. Quote Link to comment Share on other sites More sharing options...

I would document the aftermarket equipment on the repair order and tell the customer to return the truck to stock and re-evaluate the concern before even THINKING about touching that truck! /forums/images/%%GRAEMLIN_URL%%/2cents.gif Quote Link to comment Share on other sites More sharing options...
2003EDGE Posted February 13, 2007 Share Posted February 13, 2007 The oversized intercooler, piping and boots are not going to cause a boost at idle. I have seen where the ebp sensor will go bad and cause the turbo to think that it needs to be at a higher boost level. I have also seen where there are guys with programming that will actuate the vanes in the turbo to act like an engine brake. However, this is only active when the vehicle is moving. I would look at the relation between the EBP sensor and the turbo boost. They should be within I think 4 psi of each other. Quote Link to comment Share on other sites More sharing options...
