I will give this a try, Thankyou.

Hi all, I have a strange boost thing happening on my 2004 WRX and wondered if anyone had experienced anything similar. I can take the car out and it’ll boost to somewhere between 12-14psi sort of level (hard to get the exact figure with position of gauge), if I am easy on it then it’s fine, if I happen to floor it and keep it on boost for a few seconds, say overtaking a slow moving car for example then it’ll limit the boost to 7psi for a few miles. After which it’ll be back up in the normal range until I do something to upset it again. Could this be a boost control issue? Maybe a faulty part so maybe it’s over boosting slightly and chucking it in to limp mode, or maybe something else. No modifications other than a dump valve and the boost gauge. Running on super unleaded 99% of the time. I don’t take the car out every day, maybe once or twice a week as I have a daily driver that’s more economical on the fuel. Any Input welcome as I would love to get this solved asap. Many thanks
