So for starters initially the gauge would read 43.5psi even with the car at idle. Innovate said to do a altitude re cal. I did that today and it no longer reads 43.5psi at idle but now it flashes between 0.0 and -7 and 43.9. I'd figure at idle it should put a steady vacuum and not flash between those numbers. Heres the kicker I didnt wire this up or plumb the vacuum hoses . I've attached the youtube video of the gauge . Do yall have any suggestions
If you feel the wiring is wrong or the plugs aren’t sealed go back and re work it . Re set and re cal once more before determining the part is defective. It shouldn’t pull any vacuum unless your on the throttle or you have a leak . Goodluck.

make sure you have a good ground connection... does that gauge use it's own map sensor?... I had an innovate psb-1 that used it's own map sensor and you could not use the map sensor used to run the car, I would check that out also

all the videos I've seen of these things running on cars the gauge is in vacuum as soon as the car is on and running. I would imagine if there were no vacuum when the car was running things like brakes wouldnt work very well. is this not correct?

Yes it runs off its own map sensor. Where does everyone T into a vacuum source for these gauges? In the morning I'll get a picture of where the map sensor is and where its hooked into
Kind of hard to see but basically. There is a main hose that is tee'd off the brake master. That is then tee'd off to the fuel pressure regulator and it goes across the cowl to the map sensor for the boost gauge and then is tee'd and y'd into what looks like a hobbs switch (the silver disk looking thing there are two of them) and then that big line heads down under the headlight on the passenger side to what I can only assume is down to the BOV.

it could be cleaned up that's for sure, a vacuum block would be a good idea that way the only tap is in the booster line and you can feed everything else on it's own dedicated vacuum line... check to make sure those zip ties aren't too tight and restricting flow and double check the wiring to make sure the connections are solid and make sure you have a good ground... if all that checks out maybe the gauge is bad
innovate mtx-d boost gauge help
