I don't like my Dawes Device Boost Controller Anymore
After installing my Defi Boost gauge, I can see how the dawes device rapidly opens and closes to control boost. The Defi gauge is so sensitive that the needle flutters when at your max boost. I think its the dawes device's valve opening and closing that makes this happin. This is what the needle looks like: Hold one finger in front of your face, now move it back and forth about two inches as fast as you can. Thats what it does. Its anoying and seems like a pretty sloppy way to control boost. I think I'll get an electronic boost controller instead.

mine works just fine, had it for two years now....rock stable boost control (ok, I get a little creep with the midpipe, esp in cold weather) quick turbo transition with absolutely no spike (home depot valve on the pre-control line)
i think you may have another problem or perhaps the valve is sticking
the dawes valve does not "rapidly open and close"...I think you are confused...it is basically a check valve that opens at a pre-set point to control pressure in the wastegate actuator line....see R.R's description http://www.rx7turboturbo.com/robrobi...boost_note.htm

Many boost gauges come with a very small pill insertd into the pressure hose. This is used to prevent/reduce pressure pulses like the pulsation dampener does for the fuel system. When I test removed mine from my boost gauge, it would flutter. Verify if your Defi is suppose to have one or not.

Chuck's right, make sure you have a pill. I don't have one in my PFS gauge and have been meaning to get one. I have a dawes controller and my gauge flutters, but it also did that when I had the home depot boost control. Where can I get just the pill from, anyone know?

The problem is not that bad... I'm just being **** on this one. I think i might have made it too sensitive by using 6mm vacuum hose with less than 1 ft on each end of the device. Maybe if i use more hose it will cut back on the sensitivity, but then I would probably get boost spike. Oh, and no Defi boost gauges are not suppost to have pills in them, but thanks anyways.
btw, gsxr1000...
I not confused on how the device works. Your acting like i thought the dawes device worked off of a duty cycle priciple. Brother Please!

FDRacer.....these are your words, are they not? you were confused, you just don't want to admit it
the dawes is just a little pressure relief valve, it does not "rapidly open and close", I talked to the guy that created it
