OBD Bluetooth tool for boost presssure measurement ?

Lately I have felt like my car is lacking power so I found my Bluetooth obd tool and got some boost measurements while driving. I have dinan stage 2 on my EWG n55 and can only get a Max boost pressure of 8psi and then it falls down to 7ish and holds. I have checked my vrsf charpipe and connections and I can't find anything obvious.... I don't have any codes.

Anybody else use a Bluetooth tool to read boost? I am assuming I have a leak somewhere...

Thank you.

It would be best to do some logging to see how far off target boost you might be. Aside from that its hard to guess just based on boost readings since the DME will adjust to different conditions and variables.

on top of that, the dinan stage 2 is a piggyback like jb+/4 right? so it will not show actual readings, just what the DME thinks it's reading. does dinan not have add-on monitoring/logging software like Jb4 so you can get actual readings? if not you can try doing a smoke test to find a potential leak.

Ahh I was wondering if that would be the case using the OBD tool to measure boost. I'll have to do some logs. Thanks for the input.
