I have an Isspro EV2 60psi boost gauge in my truck, piggy-backed with an EGT and Tranny Temp Gauge also. All three are Isspro EV2's... Well today I noticed that my truck was all of a sudden making 25lbs of boost, so I stopped and now my gauge seems to be stuck at 10lbs. It won't go any less than that. It still works perfectly other than its showing I'm making 10 more lbs of boost than I really am. It still rotates down to 0 when I cycle the key, so I don't think the gauge is bad. Does this sound like the sending unit? I don't even think they have been on the truck for 10 months. And I can't find anything about thier warranty.
