ok guys, the other day i was driving to the beach and i veared on to the interstate and got on it to see how the car was running. well it felt kinda weak at first then it happened, i floored it and my car wouldn't go past 4k rpm and it took a while to get to 80mph. keep in mind i was going 60 when i floored it. so i pulled in a gas station to take a look. when the car is in neutral and i rev, my boost gauge reads 0psi. i cant build boost and when i'm driving i dont hear my turbo's spooling. all i have done to my car is just BPU. any help would be greatly aprreciated.
