Message Lets see...

Stock setup the wastegate is fed compressor outlet pressure (through an orifice/boost jet that creates a small pressure differential). When the pressure (at the wastegate) reaches some value (I think I read the stock WG is around 6-7psig?) the wastegate starts to open to slow the turbine wheel (thus compressor wheel, lowering boost).

When you install an EBC, the WG is left at atmosphere until the EBC senses pressure above the set point, at which point it opens a solenoid between the compressor outlet and the wastegate, thus slowing the turbine, lowering boost.

Basically, your turbo wants to stop at 7psi, but the EBC lies to it until it reaches some other pressure (say 14psig) then says, oh by the way you're way over 7psig you may want to slow your roll.

So basically the EBC is a tricky deceiving bitch.

How is it not?
