I am getting the same thing.... going to get accessport and i'll post back with results.I just installed a used Perrin Intake on my 09 WRX...
Current Mods include SPT CBE and stock DP.
any reason there is a little lag around 4k to 4.5 rpms? otherwise i like it and it sounds like i have a BOV installed.
Whats your guys' input?
