well after about 3 hours of racing i realized my car is only running about 8 psi. 10 psi in 5th. I have a BC and it was set at 11 psi (earlier in the day). My first thought was a vaccume leak. but the car did not act like it had one The idle was fine and it didnt try to stall. I will double chekc in the morning. Anything else i should be checking?

do u have stock intercooler pipes? if u do, maybe they expanded due to the heat, thus causing a drop in boost. good luck with it all.
