1. ) installed three sets--1st. set went perfect 2nd and 3rd sets something went haywire with the pyros. too much headache - took them out and replaced with A/M Colbalt just my bad experience
2. ) I puchased the DiPricol Optix boost and pyro guages around May 15th. The next day I am having problems with the pyro - works ok for 30-45 minutes and then has a mind of it's own. Turn the truck off, restart, and it works fine again for the same amount of time. I contact the selling dealer the next day after installation (4 days after receiving shipment) and they can do nothing for me. I was forced to send directly to DiPricol for "testing. " So far I know nothing. Will be calling again tomorrow.
The last 2 weeks, the boost guage has a internal buzzing noise over 15-20lbs of boost. I am not having good luck with these guages. Never had problems with Ispro's in the past.
The guage did not function correctly from day 1. It has been years that the selling dealer or merchant has not sent one out right away to replace a possible bad or defective unit. (In anything I have purchased). This may very well be the DiPricol policy, and that is fine. All I know is I purchased a boost guage, pyro, and pillar mount for $360. 00 on May 14th, and have yet to have these function correctly in my truck. The pyrometer has been at Dannin since the end of May, and I had to call them to find out the unit has been dropped or whatever. It could have been done my shipping department or UPS, I am not sure. One thing I am very interested in is why the warranty sticker was missing. I have no reason to remove it.
As for the guage not working, I believe it has something to do with the servo motor. The guage would always work fine for 30-45 minutes and then act up. I could turn the truck off, restart it, and the guage would work fine again for the same amount of time. I double and triple checked the wiring. I have installed about 10 sets of various brand guages over the years.
3. ) I am having the same exact problem with my optix on my pyro. To be more detailed it really only happens when I am towing and getting up to around 1300 degrees. As soon as I get that hot for a few seconds it will go crazy. It will go down to zero then go to 1600 then 1000 etc. THis happens really fast back and forth. Once I crest the hill and let off the pedal everything goes back to normal. The only reason I'm not more concerned is that fact that my truck is stock. Keep my posted. I need to get this fixed also.
4. ) Have had similar issues here. My boost gauge rattled since new. Dealer took it back and replaced under warranty, but the new one rattles the same as the old one (if not worse... ) Danion/Dipricol said it is "normal" for the gauge mechanism to make noise... I would like to try the snubber thing as a last resort... .
I am also struggling to find a sqealing noise that is somehow related to the boost gauge. I replaced the entire plastic line and compresion fittings, but the "squeal" is still there anywhere above 20#. Any suggestions???
I'm pleased by my EGT, but twice in the few months Ive owned them I've noticed the gauge reading artificlly high. When I let the truck idle down it wont go below 500f. Turn off and back on and its right at 300f where it normally is. Weird, but so far not a big deal.
5. ) Having issues with my Optix pyro as well. Works fine for about 30 minutes. . Then is all over the map. . Sometimes over 200° off! Good thing I have a second Pyro!
Also, when I talk on my CB... Needle goes crazy. I called Dannin and they are working on the problem.
6. ) Thumbs down DiPricol
I purcased the older Dipricol EGT gauge (white dot center) which was supposed to be a match to the 2004 dash. It has never provided uniform light and is extreemely bright under the MFG name, yet dark in most other places. Yes I did check to verify that the LED is working. I contacted the company I purchased it from, they just put me off saying that is the way it is (guages aren't perfect).
I was looking for a new gauge when Dave Meheen (Diesel Power Products) directed my efforts to get in touch with Dipricol (Prab - owner) who told me he was going to fix this and kept putting me off for over 4 months - then Prab turned me over to his daughter Jenny who said I am going to sell you a new gage at dealer cost (what about what I spend on the original gauge)... . BS This was over a 5 month span.....
7. ) I just swapped out my DiPricol EGT gauge with an Isspro due to the poor lighting. If I had to do it over I'd get the Isspro's.
8. ) Also, my EGT guage DPP sent me was DOA, so I am waiting on another. May want to wait a bit and let DiPricol figure out the problem, apparently quite a few have been DOA.
