Ok, I just got some nexus gauges installed, Boost/EGT/Oil Temp. My boost pressure is maxing out at 12 psi. I was getting 1.4 - 1.5 of boost before the install. Car feels ok, but i haven't driven it for about a week and can't really tell if there is a problem or if the gauge is just reading wrong.
Does anyone know if you can test/calibrate these gauges or how can I test my boost pressure to see if it is holding at 12 or 20 psi?
Thanks,
Mike

Also, EGT Readings, Sit and idle 1000, is this normal? I tapped my manifold at cylinder 2.

 

Ok, maybe I figured out how to calibrate my nexus gauges. My boost gauge seems to spike at about 20-21 lbs and then tapper to 16lbs or so during WOT. Now my oil temp gauges seems to read 155 give or take on oil temp at temperature, does this seem right?
Also my egt seems to be sitting at about 900-950 at idle/up to temp, is this right? I have done a search and see where 1250 at normal driving. But I really can't find an answer from D Buschur or a shop with lots of experience. My car has a tomei manifold, o2, dp, stock cat and greddy ti-c cat back.
Thanks,

 

Looks like my EGT Reading are normalizing to around 1200-1300 during driving.

Now my oil temp barely climbs. The highest I have seen is 160. What is a normal reading for oil temp?

Thanks
