Turbo timming recommendation?

2* per psi is way too much to pull.


I ended up with 25* locked out(.9 per psi), drove it for a while like that.

Picked up a 6530 with a 3 bar map, now running 35 and pulling 10*starting at 5psi to 25 at 10psi. And this isn't an exageration, it picked up probably 50whp under the curve just by doing that.


.7-1.0 per psi is a good start.



What engine?


What heads? Closed or open chamber?
