Back pressure ?

[mclean]

Yea with the key off it reads 0 on ebp so should I look into a wastegate at 45psi boost 60 psi ebp?

and it is 0 with the key on and engine off as well?

Yes the ebp is 0.

The H&S already subtracts the atmospheric pressure unlike the DD and SCT IIRC. 60 pounds is not high. When you start hitting around 70 you should be cautious. Was this at WOT?

Yea it was wide open this morning I did it again and it hit 48psi boost and 63ebp.

my truck is showing high ebp numbers as well. what is a safe peak number before needing a wastegate?

70psi backpressure is what I wouldnt want to be above (84 w/ Barometric added in)
