Manual boost controller experiences . . .
Hi, i'd like to get some input from members on the forum who have manual boost controllers (Particularly members who have similar mods as my rx7). I have a Automatic and would like to keep the "hold" feature so a ECU won't do. Thanks guys!

I have a "Home Depot" needle valve controller. Installation was pretty easy. Just pull the intake out of the way, and swap the wastegate line out with the one with the controller in it. Adjustment took about 45 minutes. I wanted to make sure that I didn't get too much boost, so I adjusted it slowly. That meant making a run, stopping the car, popping the hood, and turning the valve for each adjustment. Once I got it where I wanted it, its done. Just leave it alone, and don't worry about it ever again. The nice thing about the needle valve is that there are no moving parts or electronics that might go bad. If you opt for the needle valve, DO NOT install the prespool controller!! Adjustment is virtually impossible with two valves.
Another nice thing about the needle valve controller is that you can make one for about $7

I followed the design that Damien did a couple of years ago and built a ball and spring valve (2 of them) ... works like a charm, absolutely rock solid boost control ... even with intake, DP, MP and CB.
Go for it!
