    Cool Can i swap boost gauges?

    I have searched and cant seem to find anything answering my question. My spt boost gauge readings are quite off, the gauge is flashing when its on.So i thought it was time to just get a new gauge.I was wondering if it was possible to just swap the gauge itself and change it to a different brand. If i could swap it would i need to do the whole process of installing a boost gauge again?


    Thanks much love.

    The gauge you buy to replace the SPT gauge will come with everything you need to replace the everything, so why not? They are very easy to install. I would recommend replacing the whole thing. I would go for Defi, or AEM, which are nice gauges. They are a little more expensive, but I am in the mindset that I buy quality parts once rather than lower quality parts numerous times (just my opinion).

    ^agreed. If you want something cheaper I would recommend Maddad. My favorite gauges aesthetic wise.

    How did you verify the gauge was reading incorrectly?

    Well I don't know for sure, but its saying that I am making 20 pounds of boost which I'm sure I'm not, and its very sporadic.I've heard stories of spt gauges going out so it was more of a theory that my gauge did. Is there a way I can found out to see if its "broken" for sure? Or does that sound like its done for?

    If your car is still under warranty have a the dealership look at it. What year is the car? Does the gauge say you constantly making 20lbs or around there?

    I bought it used but its an 09 with 55k miles.Its at a constant 20 pounds , unless I'm at idle that's why I'm thinking that its done for.

    I would think faulty wiring would be more likely than a bad gauge.. in which case replacing the gauge and reusing the same wiring will do you no good.

    so doing the wiring over again would be my best bet to get it back in working order?

    Is the SPT gauge electronic with a sender?

    Hmm.. never mind then. If it's mechanical and only reads vacuum or 20psi then there is probably something wrong with the gauge.. although flickering is indicative of a bad ground or other wiring issue.

    So scrapping it and get a new gauge and wiring would be the best idea?
