In-cabin boost controller Looking at the Turbosmart in-cabin controller for like $142.00, not cheap but I like their stuff. Do these work pretty good?
A 12$ dash mounted pneumatic regulator will do the same thing. I use an Ebay plastic mini-regulator on my turbo LS. Works just fine. Turbosmart unit I installed on a friends car worked great too... Just seems like a waste to me.

Assuming your in the ball park with the spring in your gate all you need is a dual port wastegate, length of vacuum hose (silicone is best) and this regulator. My gate came with a standard 10lb spring. (I’d see 9 on my boost gauge on spring alone) I had a range of 9-20psi with this ****. I had to up the size of the spring in the gate to get more than 20psi.
You would remove and plug the gauge. The **** has a nice locking feature. You pull the **** up to unlock and turn it clockwise to allow more boost to reach the top WG port. That will increase the boost. Allowing no pressure to the top port will give you your lowest boost.

I built a regulator unit at work with a special low pressure spring that doesn't make the adjustments so touchy. Its mounted in my dash where my cigarette lighter used to be. works like a charm! I'll take pictures tonight.
I've haven't seen a "touchy" setup done like this with these regulators. Usually a half to 1/4 to 1/2 turn turn for a pound increase. I've never seen a relief type regulator small enough to go in place of a cig. lighter? Are you using a "boost bleed" type of control? They can be very touchy.

Can you guys comment on the gated-spring action on these allowing boost to come in faster? I never tried one (or any boost controller for that matter) but the one time I discconnected the compressor line to the w/g and just relied on spring pressure, I was very suprised at how much more responsive the turbo was at low rpms vs having it connected to the compressor. I would imagine using a controller with a spring has the same effect??

I like this setup. I've used it quite a bit. (pretty cool website too. wasted alot of hours there!)

Here is another way, very cheap and easy, But requires a bit of trial and error tuning so you don't over boost initially.
"If you want an even higher initial peak boost value, simply T into the wastegate line a small sealed volume, such as a small aerosol can or the pictured camping water container. This will allow boost to flare a bit, as the can needs to fill with pressurised air before the wastegate starts to move. This can be a surprisingly effective modification - on one Charade Turbo, fitting just the over-boost can was enough to give wheelspin on every full throttle first-second gear change!"
I suppose you wouldn't have to use a cheap plastic regulator. They make much nicer ones. I've never had an issues with the cheap units though. I have a name brand steel precision mini-regulator. It's a heavy bastard.

If you run a regulator with a std 125 lb spring it gets very touchy when you're doing adjustments for +/- 1-2 psi.
I'm adding pressure to the top of the wastegate diaphragm like the pictures above show.
Hello. I hope I'm not being a bother. I had a question for you regarding the post below.
I recently purchased a Borg Warner S476 from Forced Inductions and these don't seem to have a pressure fitting on the turbo. Would I be able to run the hose that's supposed to go to the pressure fitting on the turbo based on your diagram straight to my vacuum block instead? Would that work or do I need to drill and tap a pressure fitting on my brand new turbo? That idea frightens me. Please let me know what you think. Obviously I'm a 110% newbie in the turbo world, so I thought you might be able to assist. Thanks for your time.

It is best to get it close to the turbo. From the vacuum block may delay the speed it reacts. Tapping the outlet port really isn't a big deal. You could add a nipple to the tubing instead but the cast aluminum is pretty easy to work with. Tapping from the vacuum also adds the issue of the piping volume and IC pressure drop. Pre-IC at a minimum I would think.
