Hey everyone, a buddy of mine had his truck tuned locally and while it seemed to make good power on the dyno, on the street it would just fall flat on its face in the mid-rang making it less than desirable for street-ability. He is currently working with a remote tuner which is taking some time as expected being in two different locations, but we were curious on the PE and BE settings and wondering if this is the culprit to the issues he has been having. Below is information on the truck and screenshots of the PE/BE and the VE table. I have cleaned up the VE table some, but after looking on multiple forums and sites it seems that PDB setups are not really talked about much in comparison to centrifugal or turbo setups.
From what I have been able to find, there are some debates on the PE/BE and which should have a lower AFR due to the setup being PDB and the 2 second delay on the BE. Any input would be greatly appreciated!
Thank you in advance for any input or guidance you can provide!
