Hello everyone, in short i was driving my car on a track session and after a few laps, the car looses power and wont build boost past 9psi. I have a '13 Sti with 1500 miles on the odo, recently changed the oil with Subaru fluids. The car has an AP tuned to 17 psi, very mild tune. Everything is stock except a grimmspeed EBCS. The car was running perfectly the first couple of laps and now it just wont build boost. I didn't over rev, didn't miss a shift, nothing weird happened, the temp never pass the half way point. I'm seriously depressed, i treated the car so well and couldn't even get a track day out of it. The engines also seems to wobble, side to side, as if it were loose. I never before had looked at my engine so closely but this seemed awkward. I would really appreciate any help at all you guys/gals could provide. I removed the EBCS and returned the original back, but there's a good amount of oil going from the TMIC to the throttle body, coming out of the turbo's compressor outlet, hoses from the compressor side pressure source to the ebcs had oil too. After returning back to stock the car still makes 9psi. The car doesn't smoke out of the exaust, or the oil cap in the engine compartment. It drives normally just lacking power, no lights on at all.
