thoughts on crappy boost gauges

[Austin@STM]

AEM guages are about as good as it gets, and i think they are one of the best looking guages.

Yeah, I have 5 AEM Gauges except fuel pressure. Wondering if I need it or not... Hhaha!

while we're on the topic of AEM gauges, do you guys have any experience monitoring knock with the AEM serial gauges? Do the gauges "hold" the maximum knock counts for very long or does it just flash and then disappear?

I had prosports and they are incredibly worthless. Just installed some stack gauges, pics and review here

i honestly think that the guy running prosport didn't have any electrical engineering experience. he very likely asked the chinese guys what he wanted in very vague terms, and they fulfilled his request very cheaply because he didn't specify any perforamnce criteria other than steady-state accuracy.

I'd say you're right.

I got the two gauges for a little over 100 bucks. They did something different for the opening ceremony, I thought they would do the same thing. They might be pretty to look at but to read them kind of sucks. I liked the autometer better. I guess I would have been happy with the fuel pressure one if it read correctly. I was low on cash so I just decided to give them a shot knowing I might be pulling them out before long. Very cheap = Very cheap.

I have seen rings blown on my friends car from his bad mechanical boost gauge. It was an autometer mechanical and he had no reason to assume it didnt read right. It looked like it worked fine but didnt read right. He was set at 17psi, with all proper fuel mods, according to his gauge. but after a couple passes at the track his rings were gone. When he got rings fixed, I let him try my boost gauge (another autometer pro comp I used for years) and we compared the two gauges.

His autometer read 8 psi, mine read 17psi. Then his read 16psi when mine read 25psi. SO long story short is make sure your gauge is in working order. DOuble check it with another or a source that you know how much is being applied before going all out. And if something feels wrong make sure boost is right.

A crappy gauge cost a whole engine rebuild in only a couple passes. And it was weird because he turned it up little by little but it still kept reading low so he thought it was okay. It barely went up and was still in pump gas territory. But it just went up alot slower than what was correct. He was running 17 psi on pump in his dsm on the bad gauge which was prolly over 26psi in real life.

BTW it was a newer gauge so don't assume just that its a new mechanical gauge that it is 100% accurate. Bad stuff does still get pass quality control.

This is my option as well:

I have all aem gauges, very satisfied with the results and accuracy of the digital gauges.

Another reason why I will not buy Prosport.

Man I have an STRI I guess I'm not that worried about response time but that is nuts! I have an STRI mechanical before the DSD and I think it was about the same as the DSD. I wonder why they are so slow.

So should I stay with getting Defi or get AEM?
