sti intercooler
I just purchased a sti intercooler for my 06 wrx that has just a few mods, access port ots stage 2 map, cobb intake, bov, and down pipe. Im putting on the intercooler in a few days, but just wanted to get a sense of what gains should be expected with this intercooler and my setup? thanks!!

first thing let me tell you that the ots stage 2 map does not call for a bov. you need to put the stock bypass valve on,or get a street tune to make a realtime tune with that bov that you have on there. im running everything you have except i have the stock bypass valve with a full catless exhaust system (up pipe also).i put a sti top mount on months after i was stage 2 ots map and really didnt notice anything. but i did just recently got my car street tuned on stage 2 and now im pulling 18.5 lbs boost on the stock tdo4(dont know what turbo came with your wrx,it may be the same). hope this helps

He is right about your BOV. I am stage two and just put a TurboXs tmic on a few months back and noticed a little faster response in my spool up.(not much though)

^TMIC will do nothing at best but help the charge temp without a (re)tune.

My car was tuned with it than it was yanked to sell:(

0 hp. You will need to get tuned to take real advantage of it. And remember that intercoolers are not power makers, they are support mods.
