Right now I have a an HKS EVC IV, but it is a pain to set. I was thinking of getting the twosrus MBC. Will this be any worse than the HKS unit, in terms of reliability and controlling the boost?

Nothing will give you better booast control and reliability than a ball/spring MBC like the twosrus.

I have the EVCII and love it. It so easy to set, and love it way better than all the other MBC's Ive had.(disclaimer: Ive never owned a Twosrus MBC). I have 3 settings, the first two you adjust with a small screw on the back of the unit, those two took me about 5 minutes to get where I want. The third is an adjustable knob on the front so I can put it wherever I want within seconds. This EBC along with my 46mm wastegate holds boost rock steady without an ounce of creep or spike at 10-17psi that Ive tried so far. What makes the EVCIV such a PITA?

Its a pain, because you have to redline it in third or something like that to set it.(is this correct?) You just can't turn the knob and go, I think. How long does it take to put a MBC in? and will the twosrus unit fit with a TD06? Just looking for 15 psi, probably won't be goin higher than that.

It shouldn't take more then 30 minutes ro install any MBC. Its just a valve that goes in the hose between the turbo and the actuator.

And any MBC should work with any turbo using a pneumatic actuator.

MBC is annoying during spring and fall depending on where you live when temp changes are frequent.

Here in NY I feel like I'm readjusting this thing everyday...

Because I drive see my boost has shifted, stop, open up, screw it one way or the other. Drive, check boost.

It's less convenient that being in the cabin with a knob. Esp... since I live in nyc area and there's often not a convenient area to adjust boost.

Hmm maybe I should plumb it into the cabin.

With a ball/spring MBC. spring tension controls boost. If you have 15 psi tension on the spring, it will open at 15 psi in January, and 15 psi in July.

The spring is unaffected by temperatures.

That would leave me at a loss to explain boost changes I have experienced during altitude and temperature changes???

The spring is? however there is a difference between 15psi @ 30 degree F and 15 psi at 60 degrees F.

And my boost has changed in diff temps, and all I do is move the spring, which happens to be a 2srus controller.....

so I'm confused then bill, seems oldster is too
