just got my autometer boost gauge installed today... i have a Greddy profec b spec II, so it's got a digital readout of the boost. it showed peak boost at 23.6psi but autometer boost gauge's needle wouldn't pass 20psi any ideas besides the gauge is a defect?

 

install error

 

i hear autometer gauges arent that accurate

 

You answered your own question in the title.

 

I can't find the thread. I saw the thread a few days ago talking about how accurate the greddy profec is. I think at the most through out the psi range the profec was off by 0.1-0.4 off at the most.

 

it is pretty accurate, but it's mounted close to the cig lighter, it's hard for me to look at it while WOT...

 

the profec IS accurate. electronic boost gauges ARE accurate...if you have an electronic one and its not accurate, then you wasted your money. lol

 

Tie your gauge into the profec vacum line. That way you could atleast see how much your gauge is really off. If you know how much you should be ok. Or just get a new gauge

 

your out of your mind.....autometer guages have been around forever. They are quite possibily the best guages $ can buy.....theres a reason why they use autometer in top fuel and funny cars, because they have to be the best and have to be absolutely accurate.

 

There are many threads on here saying that autometer gauges sucks, I would stay away.

 

am i out of my mind yes...i hate doing hw, which is what i'm doing.

autometer sucking? i would stay away. sure they're in top fuel and funny cars. but there are people who say that they suck. i'd rather go spend a little more money to get another gauge. there's prosport guages which are really accurate (especially for the price)

i dont have evidence to back up the statement of "autometer sucks"...but there are threads and people who believe so.

 

ive got one and im pretty sure its accurate. I say this because i hooked it up with the stock boost controller and it read 19 psi, and from i hear thats what these cars push stock but i dont no

 

autometer sucks donkey nuts lol!!! j/k i hear there ok but i just dont like em, i prefer the defi's there all around better and they illuminate in the dark ..go with the :P godo luck

 

autometer sucks....end of story
