VDO is great, had them in my DSM too! $29 and was more accurate that $100+ Defi's.. go figure lol

 

Well speaking from experience my Defi BF amber Imperial boost is off 2psi. I still think it was worth the money for me because I do use my peak hold and play back and above all I paid for them to match the factory guages. I mean if I had a cheap 1st gen DSM I wouldnt care how it looks but after dropping 30 grand on a car I want it to look perfect, not just work well. The Stewart Warner's look the same at night but have white numbers by day. They are more accurate and cost 1/4 as much. This seems to be what some of the big name guys are using like Dave Buschur and Al Freidman. If I could do it all over I would still get the Defis based on looks alone but if you dont care about that, then go Steward Warner. Period. Just my 2 cents....

 

AEM Tru Boost Gauge and controller seems to be right on, ayone quote me on that ?????

 

No one has commented on the Apex gauge, is it that noone really uses it or is it just inaccurate?

 

I was looking at the Greddys prior to purchasing the Defis but unfortunately they do not offer gauges that read in SI units.

 

I used an Apex'i 60mm mechanical boost gauge in my Eclipse. Don't know exactly how accurate it was, but it gave nearly identical boost readouts to my HKS EVC boost controller (after changing between units). I set my boost controller for 1.25 bar and the gauge read 18 psi on the nose all the way to redline.

This was the old EL-series, not the new(er) EL2's with playback. The gauge is pretty cheap, but not as cheap as the Stewart Warner's. The only advantage I can see over the Stewart Warner's is the fact that it's 60mm (SW's are all 52mm).

They aren't that popular for Evo's, but I think most of that is the bright blue backlighting that doesn't match the Evo interior lighting.

 

they do now. i know this for a fact since i have a 30 psi greddy gauge in my car right now. if i knew how to post pics i would.
*edit*just wanted to let everyone know, the 52mm greddy boost gauges are available in 30 psi or 2.0 bar, the peak hold/warning 60mm gauges are only offered in bar. hope this clears it up.
52mm
60mm peak hold/warning

 

defi guages read high.....i won't put anything but autometer in my cars!!!

 

Now im just confused

 

it's mostly preference. everyone likes to think that their gauges are the most accurate, but the only way to know is to hook it up to an air source with a calibrated gauge and see. even two differnt gauges of the same type and brand can read differently. generally, electronic gauges with map sensors are more accurate than mechanical since they self calibrate(zero out), they usually only read wrong if the sensor is bad.

 

Would not how well you install the gauge also be a factor?

 

gotta love defis gauges :P

 

no alarms or peak. also, no EGT. I called them about this and they have no plans to offer those feature or make an EGT gauge at this time.

 

i thought this thread was for an accurate boost gauge?

 

Indeed honda
