Strange that, it should be running 150bhp standard as its an AGU spec engine with a KO3 turbo...same as mine.
Sounds like you've been played by the dyno lottery!!. Without wanting to rain all over your parade the KO3 wont make 200bhp, it just cant do it. Dyno runs can be 'tweaked' to give punters good gains, I'd eat my left arm if your car's making over 200bhp on a KO3, sorry.
My cars running a KO3 turbo with a green cotton panel filter, Custom Code map, Forge TIP and a stainless straight through exhaust system... the very reputable place thats done work on it and mapped it told me in no uncertain terms that it wont make 200bhp, the turbo's just not big enough to deliver it as the KO3 is pretty much just a hair dryer. I'm not alone in thinking this, its pretty common knowledge that the KO3 wont push past 200bhp.
