[s-cars] no boost, turbo starts to spool - but goes no farther

[Jake Gaty]

I have been having nothing but problems with my Ur-S6, the PO really promised me a great running car, but really he was just milking money out of me. I was driving on the freeway the other morning passing a car in 5th gear - the car started to boost like normal but then when i was parallel with the car my boost cut out completely and i was stuck with no power. Startled, I got to my destination and turned the car off. When I got back in a number of hours later, the car boosted just fine again, for about a pull, but then the turbo would spool no longer.

the only thing that has changed performance wise in the car was a custom exhaust that was put in about 3 weeks ago - consists of a magnaflow Y pipe after the cats into 2.5 inch piping to a straight through muffler in the rear.

I dont think that would be causing any issues but I just thought I might put that in there
