Greddy Electronic Boost Controller Question

[Deadmoans]

I believe my greddy electronic boost controller is not working.

I called greddy for some troubleshooting tips. Checked all the connections and made sure it was properly installed, checked the dip switches on the back of the controller. Everything checks out, except that my boost gauge says I'm still boosting 25psi and I have the controller set at minimum.

Now this controller was installed probably 5-6 years ago when my dad had the car.

I have not checked the boost gauge set up but it sure seems to be consistent in it's readings.

Does anyone have some ideas. My mods list is updated if you need that info.

Have you tried another boost gauge just to be sure it's not the gauge, and are you positive that the boost controller is plumbed properly? Also, very clean car! Is it still a 7-bolt?

I would try double checking all the vaccum hoses and connections, maybe one can loose? Nice pics of your Car bro... Looks good!

Thanks for the compliments!!!

Yes, it is still a 7 bolt.

I did check all the connections. I have since found out that the filter on one of the vacuum lines to the controller has a filter on it - could be plugged I guess. Plus this is the "old school" Greddy Profec B.

Maybe I'll play with the boost settings and see if they go up.

Gotta tell ya, I'm thinking going back to a nice simple manual boost controller.

Switch to "high boost" and set the controller in the middle for boost and gain. Do a 3rd or 4th gear pull and let us know what happens.
