    Update. Today I took the procharger belt off and drove it n/a and it still does it so its not boost related

    Do a data log and lets see what it says.

    Tuning software products will have a data logging capability. Some companies will offer devices that can be used to load a tune but are not tuning s/w. These devices can have data logging capabilities. Absent these tools you might want to find a good dyno shop near you and take the vehicle over there to reproduce the whoops on the dyno during a pull, while data logging.

    After the pull review the data for what is or is not happening and then take the necessary steps to correct it. Once you know the origins of the problem then you will be better prepared to go about correcting it. Right now the only thing possible is make a guess at what you think is causing the problem, make a change based on the guess and see what happens. If you guess wrong, then you start over and guess again.

    If you can not reproduce the problem while data logging either on or off the dyno, then you are going to have a long search process stretch out before you.

    Until you can get and learn how to use the diagnostic tools to determine what is going wrong, the best you can do is an eclectic sort of R&R style diagnostic on a best guess basis. The obvious, although apparently unavailable/unacceptable alternative is to take the vehicle to a shop that specializes in these sorts of situations and pay them to do the work for you.

    Yeah was really just looking for someone else who had already fixed the same issue usually when things go wrong especially on a popular vehicle more than one person has had that same problem

    While problems can be similar and sometimes even identical they can also easily be vehicle specific. This site tends to hav PD blown and turbo engine advocates more so than Centrifuged advocates. That is not to say we do not have Centri advocates their numbers are just smaller.

    You might want to try some sites that have a Centri blower focus. Although I suspect they will also ask for data logs you could also possibly come across someone who has experienced the exact same issues. The other good source would be the ProCharger User forums. That could easily be the most fertile soil to go digging in.

    Good luck in your search.

    It has nothing to do with the procharger I took the belt off and dc the procharger and still does it
