I purchased an AEM boost gauge and was wondering if I could use that and my stock MR boost gauge at the same time. Reason being, is that I don't want a dead gauge in my center console. Would I just tee the new vacuum line off a 2nd time from the intake manifold? Is it that easy? Or could I just go from inside the car tee it off from the vaccum line from the old gauge? I tried searching but couldn't find much about running two boost gauges.

 

Try teeing off the vacuum line where the MR boost gauge line is running (passenger side), where the second boost solenoid is located (connects to fuel regulator).

 

If you tee off the vacuum line inside the car then the AEM gauge may be a little delayed. It is best to have the map sensor closest to the intake manifold. There is no issue with having both gauges connected, although the stock gauge has been known for boost leaks.

 

yes you can use both at same time. I have the same setup
