Hi guys,

So I have a problem in regards to the lack of power of my MY09 WRX.
Just had my 12,500 km service, and few weeks prior to getting my service, I went out of the city for a drive and notice a significant drop in power especially around 3rd and mainly 4th-5th gear. Also notice that my cold air intake sucks in a lot of air but doesn't rev as fast as it use to.

Notes made by Subaru Dealer:
- Check boost rising rapidly to 15psi and holding
- Suggest removing after market products and then check performance

Also, he recommended me to remove the CAI and Boost Gauge.

Current mods:
Invidia CBE , Blitz Short Ram Intake, and Prosport Boost Gauge

Any suggestions? I'm considering whether to go back to my stock air intake.

Thanks in advance.
