Talk about an incentive to NOT use a manual boost controller...

I haven't touched my boost yet at all. its stock. I have, however, added a BR muffler delete pipe and intake.

I've had this gauge for less than a week. When I first installed it, I'd get a short burst to 18 or 19psi in fifth gear, then it'd fall to 16psi, like it was supposed to. Now, I'm looking at the gauge, and low and behold, iits just a hair UNDER the box for zeroing out... Its basically a tad left of the bottom line of the zero box.

The problem? I'm seeing max values of 16psi now and its holding 14 or 15psi. Surely this cannot be right, correct? Anyone else's car boost this low stock? Also, have you ever seen a variation from day to day in stock boost?

Personally, I think my gauge is bogus and don't trust it as a source to use for turning up the boost. Thoughts? Similar experiences? Input is appreciated.

 

I've had two autometer mech gauges in the past, one was centered at zero, the other one was slightly off like yours. But they both gave the same boost readings.

 

Cool, that helps. Thank you. I do think it would be wise of me to borrow someone else's mech gauge and see what readings I get then.

Any other experiences?

 

I have the Autometer Sport Comp Boost/Vaccum Guage that I bought from Bushur Racing. It always read at the bottom end of the zero box, but my boost readings are consistent. My vaccum at start up is 16mmhg and after the car warms up it is 19mmhg. Max boost depends on which gear I am in. Max boost in 5th gear in warm weather 18 to 19 psi and in cold weather 19 to 20psi. Tapering of boost depends on driving style. If I take it easy for a day or two and then dip into the boost, mine tapers to 16psi. If I drive more aggressively frequently dipping into the boost it will taper less (to 17 to 18 psi) My vaccuum and boost readings are consistent, despite the slight off zero reading when the car is shut off.

Did you install the guage yourself? If so, did you ziptie the hoses where you tapped in with your T? I not only zip tied on each side of the T, but also on the manifold and on the coupler that couples the rubber line to the nylon line. Just an idea, check your connections and make sure that none of your connections are loosening. If you did not zip tie, try that first to see if that is the problem. Also, if you installed the guage yourself did you put teflon tape on the threads for all of the connectors? If you didn't maybe there is a leak there. Hope this helps.

Autometer may not have the high zoot factor of some of the other gauges, but my Sport Comp always served me faithfully, and accurately!

 

I have used Autometer for a long time and they work great. Screw HKS and the rest of the JDM crap.

It zero's out everytime I start the car. It's great and super fast!

 

Autometer has always served me faithfully in the past, both the Phantom (ordered by mistake once...I hate white gauges) and the Sport-Comps.

I look at AutoMeter gauges like hookers. They're cheap, look decent, and you can always depend on them to be there when you need them most.

For the Evo, I decided to go with something different though, because everyone has a-pillar mounted gauges and I just couldn't stand them anymore.

Now I have gauges mounted on my windshield and they are sweet.
