How to gain HP with GReddy PROFEC Boost Controller - Ep. 1 of 3

[@christostserkezis8653]

Hey, I kinda wonder. I have bought this and it works great for my R18. but there are no tutorials for the MAP addon (which I have bought and connected already). any chance you can show us that?

i have the same profec bc and i notice on solenoid down of the bottom is a tiny hole, when i pressure test my intercooler piping from that tiny hole air escape, why ?

[@sbfnation2535]

Wish he showed how to hook up to twin external wastegates got it hooked up and have no control over the boost it just keeps climbing

[@DhatLex]

Do you have your wastegate plumed correctly? I have mine ran with a single external wastegate and it works fine. I would assume you would run it like a single external but just T the two wastegates into each other.

@@DhatLex ya I ran it just like it is on the instructions I’ve also tried running the vacuum lines like it is on my other car with Holley efi no change I’m gonna try messing with the gain and limiter to see on if it’s the solenoid band or something

[@DhatLex]

@@sbfnation2535 have you ran the car without the controller? Make sure your WG isn’t stuck closed

[@sbfnation2535]

@@DhatLex ya it made 6lbs on gate I put air to the wastegates they moved. Do you got a diagram on how you ran your vacuum lines for your gate?

[@DhatLex]

@@sbfnation2535 gotcha, I ran mine off the directions that came with the controller. I haven’t changed it since

Does this act as a boost gauge too???

[@OddClancy]

did you find an answer for this at all?

[@efjiongco]

@@OddClancyyes it’s a boost gauge too. I have it installed and love it!

[@OddClancy]

@@efjiongco thank you!! So you'd recommend? I'm wondering does it connect to the ecu at all?

[@efjiongco]

@@OddClancyyes I definitely recommend one! It’s the best one out in the market in my opinion. No it does not connect to your ecu. Just a power source and vacuum.
