Tactrix Boost Control Solenoid (Plug-n-Play for Mitsu)
#121
No pills, and its 3-port solenoid, i think i need at least downpipe or full exhaust to make more boost?

But yes, if you don't have an exhaust boost levels that high might be out of the range you really want. I would be keeping a close eye on knock. At the same time having an exhaust (I think) can actually decrease the amount of boost your turbo is able to hold at higher RPMs because boost is a function of pressure (which would be simplified extremely as airflow x time - leakage or usage ), and if you are making your engine a more efficient air pump you are using the air in that space quicker, thereby making it harder for a turbo that is already not efficient to be efficient.
You may also want to check for boost leaks.

You could still use pills if you were using the 3 port as a bleed type (like stock) rather than an interrupt setup. In any case, you would be amazed what people will do.

Yeah I guess my tatrix bcs is toast
The only thing I can think of is that when I boost leak tested with it hooked up it may have damaged it. I don't really know how this is possible unless if I managed to put like 40+ psi in the system.
I'm running the same tune (actually detuned the boost a little and copied over my pump gas turbo maps to the alt map turbo maps in case that was some kind of bug). It was set at 22psi before...
I unplugged the wires today (left the vac lines hooked up) and it hits 18-19psi on the FP WGA like it should. Unless if anyone has an ideas I'd say I've killed it.

Dont know about the prodrive, but I purchased the ingersoll rand one and it should be here today. Hopefully I can hook it up this weekend. Only cost me 30 bucks and supposely it is pretty close to stock resistance according to the subaru boost solenoid which i assume is similar to the evos
