I just installed my auto meter ultra lite gauges and took an 840 mile trip. Gauges worked great but today the boost gauge is acting funny. When ever i get over 10 psi the needle starts flickering up and down really fast. Truck seems to be running the same and i eavin ran a new poly tube from it to the boost bolt. Iv moved the boost bolt to another port, tried the new tubing with no luck. I eavin hooked the gauge up to my compressor at 20 psi and the gauge worked great? Im lost, any ideas??

 

Bump, anyone?

 

I do get some flutter w/ my autometer boost gauge, is that what your seeing?

 

I get the same flutter on my gauge

 

I had the same problem with autometer boost gauge, so I replaced it with another one not as much but still flutters.

 

In my 04 I had put the autometer ultralite guages in mine. I had the same problem with the boost guage to. In my 05 I put the isspro I didn't have no fluttering with the boost gauges. Now on my 07 I just order the dipricol optix I will see how they work.. I got the pyro, boost, and the eletric fuel pressure gauge I hope I like them.
