when my turbo kicks in it looses power at about 5000 rpms, its like its boggin in and out. Could it be the blow off valve

 

hummmm , since when did you get a turbo on that ulgy fucking truck ???? why are you still posting here ???

 

he has a turboII now. supposedly. but since when does a blow off valve go off when your revving. i thought they released pressure when you let off the throttle.

 

actually boost could possibly be leaking through the bypass valve.

dude, there could be a million and one things wrong with your car. get it diagnosed by a professional.

most likely it is just your stock turbo is worn out. most stock turbos can't breathe past 5000 rpm anyway, especially if they have some miles on them.

 

thanx

 

so how about that picture of your glovebox emo

 

Fuel system? Boost leak?

Like said before, could be a million and two things...

 

you got a PM

 

That was the first thing to come to my mind, if your fuel pressure isn't high enough at that RPM you could have a serious mixture problem. Is it a problem with power at 5000 RPM or are you noticing that there is a lack of boost at that RPM?

 

You could be hitting fuel cut... what kind of mods do you have done?
