Procharger Help! Hey whats up guys I recently traded my Camaro for another one that has a procharger on it. I know for a fact that it is a D1 Headunit and it has the 8 rib kit on there it's also got the big read blow off valve and race intercooler. I talked to the tuner who tuned the car and he said at 7lbs of boost it made 498 rwhp. The car has Long Tube headers, Offroad Y pipe, Magnaflow Racemuffler, Ls6 intake, 853 heads 
, and its a stick car. However the Autometer Boost gauge only reads 3lbs? I re-checked the lines to the gauge, all of the clamps and hoses from and to the intercooler and they all had good connections what should i do next? I was thinking mabye faulty gauge? But before I went out and bought one I was hoping for some good opinions on what to do. Thanks for your help in advance guys!

If you have HPtuners or any programmer, log your map sensor to get a true reading of what the boost pressure is. It's an easy way to see if your boost gauge is working or not.

Verdad Gallardo 1 atmosphere is equal to roughly 14.7psi or roughly 101 kpa. So we know that 101 kpa is roughly equal to 14.7psi.
So in our cars, 0-105 kpa is generally considered vacuum. The actual atmospheric pressure varies from day to day and location and altitude, but for the sake of easy math, we'll call it anything above 100kpa is positive pressure or boost.
So if you have a max value of 150 kpa, that is 50 kpa of pressure, or roughly one half atmosphere which is then 14.7/2 or 7.35psi. I would have to suspect that from day to day, your boost pressure is going to change slightly due to environmental conditions. To look at a 2" diameter gauge on your a-pillar or dashboard that goes from -20 to +20 is far less accurate to me than looking at a log and converting from kpa to psi. Anymore, my HPtuners data logger is always attatched in my car, and whenever I drive, I log data.
I'm a newbie to this whole forced induction thing, but I'm not new to data acquisition and interpriting that data. If I'm wrong please correct me.
