I'm installing a Greddy Profec-B and I have a question regarding the hose from the IN on the stepper motor. The OUT is routed to the top of my Tial wastegate. I believe without a boost controller the fitting on the turbo would connect to the side fitting on the Tial. When running the controller would the turbo's fitting go to the IN on the controller motor putting it inline and then cap off the side of the wastegate? Or would you tee into the hose joining the turbo and side of the wastegate? Or am I way off on this? Some help would be greatly appreciated. I want to finish this off so I can start her up this weekend.

Thanks

I thought a lot of members were using the Porfec-B. Or did no-one install it themselves.

On a standard wastegate that only requires 1 hose you take the hose from the compressor side of the turbo and route that to the in.. then you run a hose from the out to the wastegate. Hope this helps

That's exactly how I was hoping it would work. The out would then go to the top of the wastegate and I would plug the side fitting on the wastegate. Is this correct? I'm actually working on it right now.

The hose on the Profec B controller- goes inline with boost guage or something that reads boost (hose on manifold/FPR).

The hose that normally goes to the wastegate gets cut in half.

Then...The side that reads boost (manifold side) goes to the "IN" on the module. The "OUT" side then gets connected to the wastegate.
