I was wanting to install one of the analogue round rail pressure gauges in my truck...whats a good one to get??..also I have got upgrade my boost gauge to 100 psi...which one should I go with????....thanks

 

After the crappy customer service I received from quadzillapower I don't recommend them any more.

 

any more suggestions?????

 

If you're willing to shell out the cash, I think the two series of gauges that most closely match the OEM cluster and also have reputations for being extremely accurate and well built are the EV2 line from ISSPRO and the Optix line from Danin-Pricol. I personally have every intention of having 7 EV2 gauges in my truck to complement my Insight once it's all said and done. The Optix are a very close second for me, though.

 

I had a Pricol rail pressure gauge that was never very accurate. Electrical interfirance like you wouldn't believe. Now I have Isspro Performax gauges, and they match better in my opinion. Also this gauge seems to be more accurate.

Just my $.02

 

Define "more accurate" please.

As in "the gauge reads off, but not as often as the DiPricol"?

I'm almost to the point of changing my gauges out from DiPricol Optix if the Performax's work 100% of the time. However, if the rail pressure gauge is still screwed, I don't think I'll shell out the cash.

I'm testing a new DiPricol harness that has even more filtration than the previous harness they sent me. The gauge operates a lot better, but eventually drifts again and requires shutting the truck off-and-on to reset it. Instead of the gauge going wacky in a minute, it takes about 20 minutes now and the magnitude of the drift is less.

 

I'd do Isspro all the way, mainly because of some of the negative things I've heard about Danins customer service. And I've had the quad rp gauge fail on me also.

 

I have the DiPricol F.P. Gauge and am very happy with it. It has been on my 2006 Dodge CTD CR for almost two years now with no problems whatsoever.

i have the isspro ev2 and it has been working good so far. looks good to.

 

I have a scout and it seems to work just fine, plus you get a bunch of other gauges to boot. And it reads everything from the computer so it's got to be some what accturate...if it's good enough for dodge then it should work for me.

2 cents

 

Isspro EV2 all the way.

 

Both the diPricol and Quad rail gauges have a history of problems. That leaves ISSPRO. Mine's been running fine for three months.

 

+2 on that, never again will I purchase from there.

 

I have a Danin.. It experience a little drift and they have been working with me to fix it, but the other 5 Danin's I have are great.

 

I vote for the Performax, but I'm kind of biased
