I have a boost and air/fuel. I was wondering if anybody else uses a boost gague cause, when I hit the NOS my boost gague reads 2pounds of boost. Its wierd, I can always tell when The bottle is low on psi cause the boost goes down a little.

 

Not me, I use fuel pressure, egt, a/f and soon injector duty cycle. Why did you go with a bost gauge?

 

well....most nitrous people use the boost gauge to check vacum leaks. the gauge tells you how hard the nitrous hits, but it won't tell you how much nitrous you have left. this is wut i heard from some mustang drivers.
