IIRC JB4 map 1 and 2 are additive about 4 and 6 PSI respectively. Stock map is about 9, so 13-15. Map 5 adapts. Been a while since is used map 5 so I can't recall what I got.
The seal between the CP and FMIC is something to check, especially if you forgot to take the o ring from the stock pipe or didn't get it seated correctly.
