Exh ratio is a TunerPro calc of Exhaust Back pressure / Intake manifold pressure (so above screen grab 13.5/10.16 = 1.3).

Gives an idea of the restrictions and efficiency of the entire system, ideally you want 1 or less (ie making more boost than there is pre turbine pressure) but normally this is going to be pretty laggy. Under 1.5 I think is a reasonable compromise from what I can find.

That's interesting. So how does it calculate the exhaust pressure? Do you add a sensor?

Anywhere up to 2:1 Is acceptable closer to 1:1 The better and use pressure at the turbo for your calcs not inlet manifold
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

Yep, for a turbo only PR then I use the inlet to cooler pressure sensor (its another TP calc :lol: ). But for this I wanted to see it as a whole with the different cooler and how it all works together at higher RPM/airflow.
