There are a number of gauges now that use transducers, could add a port, and run a gauge during testing, even in the future. When you don't just remove and cap the port.

Unfortunately, the transducers are not inexpensive, but very accurate. Instant readings, and it's possible to even log, if you have a logger. (Without a gauge)

If you don't have a logger, there are some 3rd party inexpensive ones, like the Innovate one:

Not sure if the FItech ecu has logging built in, never owned one, maybe someone else can chime in on that.

Logging is great for troubleshooting, and for tracking mods/tunes.
