If I install a manual boost controller, will I still need to make my wastegate adjustable? I'm having a hard time finding someone with the tools necessary to make the adjustable wastegate. I've looked for the tools myself, but I don't want to buy a whole set. Thanks!

You can adjust boost above whatever the stock setting is, without the adjustable waste gate. But you can't go lower, all you can do is bleed off pressure, thus allowing the waste gate to open later. As the waste gate gets old, the spring gets weaker, lowering boost, so the little adjustment in the rod is good for getting them "back to new", or close. Besides, it's easy to do, and cheap.

I have a bleed valve in my console and haven't had to touch the ATR wastegate in two years. Under WOT, I GRADUALLY adjust the boost to the desired level.

Thanks guys! I'll see what I can do. i found a cheap MBC at www.DawesDevices.com $35. Looks pretty good, what do you guys think?

That is basically a grainger valve as we so often call it that costs less than 4$ along with some hose.

I would think you would be better served by something more like a bleeder valve...a mini-air regulator valve makes a really nice one. Long ago, we used to used aquarium valves...those were really precise!

Norgren has a line of them...the one that you get from Turbonetics is the Norgren R07-100-RNTA.
