 Power loss..... today i noticed a severe power drop in my car, still boosts 15lbs, severe turbo lag, horrible throttle response,and hear compressor surge, the line to the bov is connected to the intake mani.cant see any massive boost leaks, brand new intercooler and piping. any ideas would be greatly appreciated. ALSO, when i get on the throttle it sounds like a n/a car with an intake. REALLY loud, its never made that sound. thanks guys.

Re: Power loss..... Maybe an exhaust leak before the turbo? between the head and manifold or manifold & turbo or a crack somewhere in the manifold or turbo.

Re: Power loss..... What RPM do you hit full boost? What vacuum does it idle at? Havea spare waste gate actuator?

Re: Power loss..... no cracks, @ idle vac is 18-20 no i dont have a spare actuator, the car ran perfect while driving it the day before, took it out this morning and i can hear the intake so much and runs like shit even at normal temp.

Re: Power loss..... i am aware of that and i guess i should have been more specific when i say i didnt really see.... i'll try... "when the blt was performed to my intercooler system, i was unable to detect any major boost leaks, i believe that the minor pressure drop was from my hokie blt... haha

Re: Power loss..... see!!! thanks jason, no i dont have a logger, and am not tuning with anything. i dont really have that many mods, and havent had the money quite yet to get a logger. so yeah im sure that may be a possibility. but cant really tell now, jumped timing, intake valves bent....  guess it'll be a while..... thanks tho man ill get back to you on that.
