Factory Boost Control VS upgraded boost assembly (pill)
Bryan, you rock. Does the OEM boost control do direct boost control, or load-based boost control? Is there any way to spread the load out between the two BCS's, so you're not constantly at 100% ?
As a testament to what this pill can do, Bryan installed the GST assembly in my car tonight. Prior to this new pill, my tune was dropping boost like crazy on the top end...it appeared to be a boost leak. In fact, it was a problematic stock boost assembly.
Once the new assembly was installed we picked up 25whp/20wtq (from the 1st tune) and were finally able to smooth out the curve. Excellent mod with great results. Final numbers were 305whp/305wtq with a K&N drop in and a GReddy Ti-C.

The two solenoids work off each other from what I have seen. Once you start messing with them you understand more.
So basically it is the exact same boost assembly pill used in the Evo 8/9? Where can i get one? Will 3bar boost control solenoid have any effects with the pill? Is it better to run a pill or boost solenoid? Does the evo X run the same solenoid as the evo 8/9? Will an adjusted wastegate have any effects with the pill? Will a boost controller have any effects with the pill? The pill requires a tune right? I am a bit confused on how the pill works. How many stock pills are there?

Had another 10 in with the same mods as the Evo in the first post (HKS drop-in filter only)
Installed the upgraded assembly and went to tuning.
This one broke 300/300 which is quite an accomplishment on our mustang dyno with such few "mods"
301whp / 300wtq
+48whp / +32wtq peak gains
The HKS drop-in filter has shown to produce great power. 100% stock dynoed 234hp/258tq. Most powerful "almost stock" Evo 10 on our dyno yet.
+67whp / +42wtq over 100% stock
