in order to advance the JB4 bef, I share this with you.

installation : BM3 stage2 sp93+ jb4 bef

after send map1 log, test personal map6 and check the log then, pass to map3 which boost slightly more.
All log looking good by terry just *A minor fuel pressure drop down low, to fix maybe lean out flash a bit down low*
I’m thinking use meth to help

Make some dragy to compare improvements between BM3 vs BM3 jb4 bef

On 1/4 mile

BM3 only : 11.72
BM3 + JB4 bef : 11.37


On 100-200 km/h :

BM3 only : 9.38
BM3 + JB4 bef : 9.11


On 0-100 km/h

BM3 only : 3.75
BM3 + JB4 bef : 3.42
