ok so i was driving home about 10 mins ago and went to over take a car on marmion. wasnt thrashing it or anything. in 3rd gear doing about 80km pulled out and gave it a lil bit. pretty much strait away my car lost power (like hitting the rev limiter) then it came back on after i took my foot off the pedal. my engine warning light was on and my cruise control light was flashing. so i pulled over and poped the bonnet. no oil or anythin outa the ordenary. i checked my boost controler and it wasnt boosting anything over 13psi. any ideas what it is befor i call subaru tomorrow?

its a my06 wrx. mods are psw tmic. eboost2. 3"tbe. everything else is mechanical is stock.
help please
