Loss of power Part 2

[BBBurban at aol.com]

Well all,

        Thanks for the info on the line to the ECU but that wasn't it.  We
checked it at all ends and they are still connected securely.  I should have
mentioned this is a un modified car except for suspension and wheels.  While
testing the car again today in a valley we did hear some turbo spool with the
windows down and the sound   bouncing back at us off the steep banks at the
sides of the road.  So what I have deduced so far is the turbo is spinning,
the by pass valve is new, and the line to the ECU is connected.  The engine
still runs smoothly, just seems to have lost that UMMMPH that it had.  Does
anyone have a suggestion where I should look next?  I am at a total loss.

Thanks all
