The boost gauge is a omori 45mm boost Gauge, Stock is 42 or 43, You have to dremel the hole a little but noting serious..then after that you have to splice the power wire from the stock to the Omori, pretty easy really..

as for using the vent, again i dont ever use it, in the winter i use the Foot/Def..

in the summer my windows and Moon-roof is open, Im a UPS driver so im in the heat all day, Doesn't bother me anymore

 

I call BS you never drive with your windows open!

 

looks good..
one question i see you get boost gauge on stock gauge panel..
do you happend to know the size?

 

looks good. any issues with the heater?
