You noticed that also? But if the BOV was opening b4 the throttle was closed than I wouldn't be building boost no? It could be just the air rushing through the pipes.
I was running 9psi before the winter and took of the controller for the winter. Now I decided to put it back in just because I was bored with the car hehe and wanted to see what would happen as far as the fuel cut goes. I'm not sure if my car is flashed, because I still have a hesitation from 4-5.5k rpm even though I went to two different dealerships and supposetly had the car flashed twice. I saw one of the dealerships actually perform the flash, atleast that's what I looked like, a guy in the car with a little computer type device.
