With the JB+ or SSTT the 30FF code indicates you are below boost target. With the JB+ you can lower the boost, or perform the free solenoid bypass. You will need to contact SSTT for help on their end. Perhaps they can make a one-off unit with less boost if someone has the problem.

If the 30FF does not trigger a warning light it's not a big issue though. Does not reveal you had a tune installed, just that the car took longer than expected to build boost.
