The boost is increased considerably over the stock levels. However, I found that the "sweet spot" for pump gas is generally greater timing advance and less boost when compared to say Revo or GIAC. Running more boost actually makes the car slower from all of my findings due to greater timing correction. The stock turbos are just too small and not very efficient at higher boost levels leading to a big drop off in the higher RPMs and a lot of heat. This motor loves timing.
There are other tricks too, some of which I haven't openly discussed on the forum for obvious reasons.
