With an auto though you have torque converter slip.
50% nozzle, arson cp3, max effort tune from Dans Diesel Performance.
You sure it's a BOV and not an external wastegate?
Here is your issue if you are running this tune on the street. This tune is for DYNO/TRACK ONLY. If you bog it down and slam your foot to the floor you are going to overfuel with that tune, guaranteed. I have the same tune for my 06, and have never loaded it since I have never had a chance to put it on the dyno since I got the tune. I watched him write my tune, definitely not a tune I would be running other than three dyno pulls or a pass or two at the track.
In a manual, with a charger where the map is wider than the engines operating range, surge is almost unavoidable while running through gears.
You know...maybe I don't know. This is my first diesel. I bought it 5 years ago...maybe I just buy stuff without knowing what it is.
A BOV goes in the intake, Extrnal wastegate on the exhaust before the turbo

:nail:
Just a thought but I would think that the BOV might be hurting more then help. I know that its bleeding off boost but everytime the valve opens up it releases the load on the turbo and lets it free wheel for a second which is probably causing it to overspeed and then boom.
I would think you would be better off with a waste gate to slow it down with all the fuel your pouring at it. Or just go with a bigger S-400 turbo to slow it down and get rid of the BOV
