Odd question but does anyone know if there is a way to look at if the injectors are in port injection or Di mode via the @COBB Tuning access port?
There is a monitor on the Accessport called "DFI/PFI Split Actual" that will report a value between 0 and 100 - 0 indicates all fueling delivered through DI, 100 indicates all fueling delivered through PI. Under most driving conditions you'll see a blend of both being used.

Amazing , thank you! Is it possible for tuners to initiate port injection only for temporary valve cleaning purposes ? As in run a full tank on port injection every 3 months so the valves stay free of crispies .

If you monitor the split you’ll see that it’s running on port injectors most of the time anyway. The DI rolls in under heavy load to help cool the intake charge for best power at high load. There’s no reason to change unless you have bigger port injectors, etc.
