So I want to upgrade to defi gauges soon, and I want to go with Defi link series but wont because the boost gauge does not read in PSI. I like the link meter series. I like the racer series as well but I notice it is not compatible with the link meter. I have noticed that some people have a gauge that looks similar to the racer gauges but with a control unit and the boost gauge reads in PSI. Help please!
