Installed JB4 but not thrilling enough ..yet
I thought my vaccum leak fix would make JB4 one hell of an experience like others have mentioned... apparantly not, that tells me there's something else going on ... Boost leak ? I've been getting that light but not all the time, I ran a leak check and found diverter pipe not plugged in completely due to oil deposits ... cleaned and it clicked on perfect no leaks, my charge pipe arm was missing the bolt causing it to move, bolted that up, looked at intercooler connections both sides look good... NOW WHAT ELSE CAN I DO
max boost = 13 psi (from logs) |

WG setting is at 80, is this normal ? My friend's COBB sets it 92 |

picture (only took >3k rpm)
filtered out <3k RPM ... you can see throttle going to 100, boost still ~13 max, IATs around 113, this was map 5, dutycycle & PWM included

also before experimenting you should really learn how to log, read them etc... it is very important you grasp 100% how the jb works and everything that is required to run a specific map. if the car is not boosting right is not gonna boost right on ANY map.
when boosting low most probably you have a leak in a vacuum line or maybe bad solenoid if you made sure there are NO obvious leaks somewhere else. Almost everybody here got through the leaking problem so just find it. i had at least 5-6 leaks over 4 years of ownership plus tons of other problems.
