just installed newer oem dv. before my vac was at 10 and i could boost 7 max, now my vac is at 20 and i can boost 9 max. this is w/ everything stock (no chip..... nathin) im assuming its because the old one was bad. im just hoping something else isnt bad. any input is appreciated

This sounds perfect for a stock car.
