Hey guys I got the 30FF code with a boost leak my charge pipe is okay just checked it what do you guys think it could be? Could it be the IC piping? Or something else?
1st 2nd 4th 5th &6th gear boost to like 5lbs of boost
And 3rd gear barely gets to 2 pounds?
Any clue why I could log my car if that helps!

Running JB4 this happens in any map I try to run 1,2 or 5

If this helps,
I have:
synapse Charge pipe and bov
DCI
Careless downpipes
STOCK fmic

Check your vacuum lines.

Also which firmware are you running?

Newest firmware requires all DUTY BIAS values set to 0, this is in the user adjustments in the JB4 interface. Your symptoms are exactly what happens when those requirements aren't correct. Start there, then search vacuum line threads.

Also make sure you don't have boost reduction in 1-2-3rd gears, this is also in the interface.

Would this be why I'm getting the 30FF code like he stated I'll post a pic of s better one this morning after work of my JB4 logging screen....

You have to update your interface to use the newest firmware . I would venture to guess boost problems started when you updated your firmware ?

Lesson here: ALWAYS read the instructions of Firmware updates. You need the newest PC interface as well, not the one pictured above.

Make sure the values listed in the column under duty bias are set to 0 as well.
