so im catless straight helix tbe

and i did the restrictor pill modd

now im under boosting

no exhaust leaks at least that i know off and for sure no boost leak, had it checked not too long ago.

anyways by doing the restrictor pill modd it will decrease risk of over boosting for catless tbe 07 wrx only

but now im underboosting

has this happened to anyone else with 07 wrx

im trying to get a stock restrictor pill but, carlson and the oakland one doesnt even know what it is. anyone know the part number for the pill and a new hose?

thanks- patrick
