Im sure some of you guys have this lag while shifting, I'm running cobb fbo e50 map still have the lag

, i know guys who is running jb4 they don't have this much as lag as i do, should run jb4 g5 with flash on top of cobb e50? i heard jb4 controls the boost better But at the same time its's not healthy to keep the boost high to the redline... or just keep the cobb and shifting early

to avoid the lag
from 2nd to 3rd i have to shift before 6300 rpm
3rd to 4th before 6000 rpm, anything below that will cause shift lag

Take a log to determine if your perceived power loss is a timing drop or lack of boost.
