The thing that looks like a turbo timer could be an electronic boost controller, which would explain why you hit 10 lbs of boost. Or someone may have shimmed the wastegate already.

Keep in mind that if you go with a blow off valve, you're car would not have as much power right after you shift without some further upgrades to support it. You can get an aftermarket recirculating valve (like the one the cars come with) which will still give a cool sound (just quieter) but feeds it back into the intake like the ECU expects to have happen.
