I installed the TRD boost gauge yesterday along with oil pressure and Volt meter. I have a question for those who have the Boost gauge. What does your read when at idle and while driving. My needle is on the vacuum side about 5 - 15 depending on RPM. I did get it to go to about 3 PSI pressure once so far. So what does your read?

 

That is where mine is also and then it goes to the middle when the engine is off.

Nice truck sgirt

 

i get 0 for my turbo mr2 using aftermarket gauges. I'm not sure how SC works but i assume it is the same.

i have Blitz gauges.

 

thats probably about right for a 4runner s/c....My WRX ran around 15 psi of boost....i heard people are pushing Evo8's on stock internal into the mid 20's dunno how factual that is though

 

Thanks for the replies and on my 4runner's comment - thanks. Sounds like yours are the same as mine. I was thinking it would go to Pressure when under throttle. I went with an Auto Meter Carbon Fiber gauge and the Lo Tek pods. It came out really nice.
