Still, I'd rather have a boost gauge that reads a little high then one that reads too low.

maybe you didn't read my post correctly... i had it checked at 2 different reputable shops... gruppe-s and eip.... and I can assume that reputable shops have very accurate gauges/transducers.... these shops make their money off of us becuase we all assume that their equiptment is top of the line....

I would rather get an EBC in your case.
let me ask u guys a question, how are u ever really going to know how accurate a boost gague really is? every single one could read something different, slight variations but variations non the less.
That's very true, and it's the main reason why it doesn't really make a lot of sense to spend a ton of money on a boost gauge expecting to buy higher quality. More expensive doesn't necessarily mean more accurate. This is true for any gauge for that matter. They're designed to be fairly accurate within a certain amount of error. Any extra money you spend is only for features...playback, peak warning, backlighting colors, etc. The Stewart Warner's are cheap, at least as accurate as the others, and the backlighting color can be changed by buying a new bulb for $3.
Some people may be convinced that the Defi's tend to read high...and maybe they do...but as long as it's always 1 psi higher than a MAP sensor reading, does it make a difference? If your gauge is consistent with itself, you can tune and the gauge serves its purpose.

The lights burnt out and sensors went bad like crazy. My friend has them in his Sti and went through the same troubles.
Just ordered Greddy electronic boost guage. It has warning range starting at 24lbs, just fitting for IX. I'm hoping the electronic versions are more accurate than mechanicals. Anyways, there seems to be less chance of the vacum line being kinked.
I've tried many VDO, Autometer and other cheap ones. I'd rather spend a little more for a critical devise.
Then, I saw AEM Tru-boost. Hmmm, maybe later...
