Huge boost after EBC install
I had a Greddy Profec EBC installed last week. Even with the EBC switched off, I hit 14.5psi, where as before the EBC install running stock wastegate pressure I would max boost pressure out to 8psi.
Anyone experienced this or know why after installing the EBC my minimum boost pressure @ WOT has had a major jump, even when the EBC is switched off or put into 0%?
Faulty install or fault EBC, solenoid etc?
Car has AAM TT system.
