according to the instructions for the Apexi AVC-R, one solenoid controls the prespool and wastegate operation. then you just adjust duty cycle at 4500rpm to reduce boost spike.

I hooked mine up to just the wastegate and use a home depot valve to fine tune the prespool. IMO it works better this way and is easier to tune.

I have the Double selenoid SBC-ID from Blitz.
Works really well and fairly easy to install.

On hooks to the Wastegate line too...

I agree on your setup. Worked really well. NON-seq now though.

BTW, your avatar's HOT!

i think the avc-r 1st gen you can mess with the boost curve, so that the spike can be taken out of the curve. Or you can induce a little spike to help turbo spool up a little faster...
