why do you need this and how do you control the vgt on it ?
Yes EGP is exhaust gas pressure.
I use this as i am controlling the difference between Boost and EGP,
if you running width lets say 50% TPS that is not enough TPS to reach full boost, then iam controlling The differential pressure between EGP and boost.
Today i use this setting
if( TPS > 0 and TPS < 10 ) max_dif_pressure = 30 psi
if( TPS > 10 and TPS < 50 ) max_dif_pressure = 15 psi
if( TPS > 49 and TPS < 60 ) max_dif_pressure = 25 psi
if( TPS > 59 ) max_dif_pressure = 30 psi
When full boost is reach i regulate this and open vanes.
