I still have the stock blow off valve that is mounted on my stock sidemount.
I was running them both i just added the hks unit on that top pipe coming off the turbo. I always see the clips that come from japan with bov setup like this.

It works very well because the hks bov is not recirculated but the stock one still is. So you can hear the blow of valve but no hesitation between shifts and no stumbling idle. It shifts so much faster with the hks bov added.

So is it safe to run it the way it is now With it spiking 10 and settling at 8 on a stock engine setup.??? Will these boost levels cause any problem for the motor?

The only mod i have really is an intake filter and a walbro 255 lph pump.
