So recently I've noticed i'm getting very little boost in first, a little more in 2nd and by 5th and 6th i'm getting pretty much normal boost. Anyone know what might be going on? I got the car about 5,000 miles ago and haven't been beating on it.

 

Any mods? Boost controller solenoid maybe

 

car is pretty much stock only has an exhaust and intake. tonight I was getting about 14 psi in 1st as opposed to the 7 i was getting earlier today so i really have no clue whats going on.

 

It may be your wastegate actuator needs to be adjusted 3-4 turns to give it more preload. If there is not enough preload the wastegate flapper opens too early and causes lag and fluctuations.

Of course, you should definently run a boost leak test to see if a hose has popped off or something.

 

Stock BCS? I bet your car is tuned for boost by rpm. You can do that in stock ECU.
