Boost leak victims (turbo) I recently found a good boost leak on my car and was wondering who all here has found some boost leaks (big or small) and how much did it effect your 1/4 mile times/mph? How big/small was your boost leak? Just wondering if I am going to pick up some power with finding this when I go back to the track. (still gotta wait a couple days 
)

I can't tell you how much it affected my 1/4 mi times, but I had a boost leak in my bypass valve. It was barely stuck open (about .100") and lost the o-ring. I was losing a little over 4psi boost. I didn't know I was losing boost until I started logging the car with a 2-bar tune. I damn sure knew when the boost came back though. Funny how you get used to a car and don't really know it's running less than perfect until you see a trap time/speed or log it.
