My JB4 logs as requested, 26.7 PSI
So people have been asking for awhile to see my JB4 logs, well here they are
Ive been messing around with DB tuning, and I still have some work to do but here we are! this is on an E40 mix, 100% meth spray. Also I have the timing trick installed so my IAT's are showing about 40 degrees higher than reality.

You are overboosting quite a bit up top because your FF is too high compared to your PWM. Play with Duty Bias to get that under control. PWM not even 100% if I read it correctly - crazy haha
I gotta get that Stg 2 :P

Lol not even! But yea I'm still messin around with the duty bias. It was perfect before I upped the boost to 27, it should be a pretty simple change.

FF is globally controlling/scaling (together with a bunch of other parameters) the PWM signal to the turbo DB (duty bias) is doing the local scaling In other words - if you get over/under boost in certain areas you can use DB to finetune. ...hope I got that right
