Turbo surge at what PSI
In an attempt to see if my MAP sensor is somehow screwy, at what boost level will surge usually happen?
The condition is running I-40W up to Asheville about a 4 mile 7% grade at 70-75 mph, EGT around 1100 when I'm accelerating out of corners. For me it starts around 11-12 psi and stops around 13-15 psi. I've read it usually happens around 18 psi, so I'm hoping that my sensor is just off by about 6 or 8 psi.
