Ok...I know most people go with a chip and that's the best thing to do blah blah blah...but I was given the Apex boost controller as a gift...so I'm trying to use it.
with the Apexi avc-r ... the solenoid only has connections for the waste gate, and charge pipe to measure boost. So, seemingly there's no need for the OEM valve (n75). This set up only allows my car to boost up to like 17 psi....any higher and blow's off and comes back down to like 10 or 5 sometimes going into limp mode....Right now the HVavle is in the intake, with nothing on the nipples for the charge pipe and waste gate....
The guy at the shop seems to think the boost cut on the ECU...

Do you guys have any suggestions as to what the set up for a electronic boost controller should look like for the 1.8T?

thanks a lot
