Default Boost Bank 2 4psi under Bank 1 - 10-23-2020, 05:30 AM
Good Morning, looking for advice or what issue to look for.

S63TU, JB4 V2 board, BCM, 93oct+oct booster, non competition.

Both Map 1 and Map 2 get Bank2 Boost 4psi or so lower than Bank1.

- Map1: Boost1 20psi max / Boost2 16psi max
- Map2: Boost1 21psi max / Boost2 17psi max

Potential Boost Leak? Charge pipe side not clamped correctly leaking or cracked?
Stock air boxes and during pulls you can hear the air getting sucked in, not sure if normal.

Thanks!

FF and FUA should learn in each bank to get boost on target on absolute target maps like map2. Tried some longer map2 runs?

No, still having the same issue. Moved to Map3 a few days ago to see if it will learn to get both on target, haven’t done a log yet to see, giving it a bit more time to adjust
