how inacuurate can gauges be?

[jezimp]

ok guys
ive read the threads about gauges, wats crap and wats not with autometer, vdo and all them, and read the test that autospeed did, but exactly how
"crap" are they?. like when they say there inacuurate, by how much, like with the boost gauge for example, just by looking at it generally with the naked eye, can you tell that its way off track for accuracy?
im about to get all my gauges soon, and can get really good deals from a mate with his work, with autometer gauges, pyro, boost, and oil pressure, is autometer really that bad that the reading on the gauge will be totally way off by a mile?

I've seen VDO Pyros be 50 degrees celcius off regularly as they are just too slow to react compared to modern digital gauges

what u get is what u pay for...

do u trust your dash meters? then why would u trust cheap gauges. the expensive and well known gauges are the way to go.

thats what im trying to find out, autometer gauges can go up to and over $300, but there not very accurate, wat do you think erik121 is a good and accurate gauge?
sometimes its not always you get wat u pay for
