Boost Question

[Hypnotized]

I noticed over the last few days that my car has been steadily holding boost betweens 12-13PSI. It will spike at 15 but holds steady at that PSI. I could have sworn it held closer to 15 and I know this car is suposed to be at 15.6 or soemthing like that. My question for all of you is have you seen this as well? I dont even know were to start to check for leaks because I havent really modded this car yet. I have a turbo XS hybrid valve on it but i even put the stock valve on and got the same. Any suffestions would be great.

Ya, mine starts at a little over 15PSI and fades to 10-12psi by 5000rpms and holds that to just before 6000rpms when I shift. I have the Forge BPV, K&N drop in with a holed up box and pretty much stock every thing else.

Thanks for the reply! Im going to get a SRI soon. The homemade one I have made a CEL com on. When I had it on though it was boosting higher and kept steady.
