Factory Boost Control VS upgraded boost assembly (pill)
^I think you are a little confused as to how the BCS system works on a turbocharged car. This mod CANNOT be used without tuning the ecu to work with it. The WGDC tables in the ECU need to be adjusted for the car to run properly and not overboost. It's a great mod, no doubt, but again you CANNOT use this without a reflash or a standalone engine management system. Altering the engine management system will void your warranty if the dealer detects it.
It is worth noting, however, that most dealers don't ever check for a reflash and so far, there are not any reported cases of a warranty being voided because of a reflash on EVOM. But technically, if they find out it's there, it WILL void your warranty, so you would still be taking a risk. In any case, I wouldn't worry too much about your warranty anyway; auto manufacturers never honor warranty claims on performance cars anyway, as they simply blame any failure on "abuse" and pin it on you to pay for the repairs. You bought an EVO; mod it and don't worry about it.

No being off topic here, but Cobb Plano used a Boost pill on my car for the tune. It pretty much just backs up all Razors info. Pre-Boost Pill was 24 down to 19-20. After the Pill was installed Peak Boost is consistently 27 tapering down to 21. The car feels incredible from 4k plus. I have had the tune and the pill a week. The car is running better than ever, and I have 0 drivavbility or Cel issues. Its really quite amazing. +1 for this Mod.
Essentially this mod is designed to hold boost to redline better. Most shops until this mod have just been using a manual boost controller and I have been planning to run my greddy profec B boost controller.
I guess my question is this, I assume the boost pill serves no purpose if you already have a 400 dollar EBC, lol? Just because it has a better solenoid to hold pressure better yes?

This is what I would assume as well, but just making sure I guess, for some crazy odd reason. I haven't looked at the boost lines setup or anything.
It's up to you to decide which works better for your needs.
Is is really necessary to have all the boost settings of the car itself? Just seems unnecessary to have all those settings when all you want is to keep boost constant. Maybe for failsafes for overboosting? I don't know, any insight would be appreciated.
Lol, I was hoping someone would point me in the right direction. I know the factory one has more options, but isn't the goal of it when tuning a vehicle for more power to simply hold the most boost until redline, well constant boost anyway? I guess I am just asking whether or not the profec solenoid is essentially doing the same thing as the pill in this case since that solenoid holds boost better? That is what people were doing with MBC's correct, or why they were using them, to hold the boost better not do more things with it?

There are rpm-based aftermarket boost controllers on the market. The Apexi AVCR and HKS EVC are two of them. Unless you have a need to change boost curves alot, the factory system does it all and sometimes better, for much cheaper.
We've found that RPM-based boost controllers work better with stock turbo and variants to hold boost better. Also, with a RPM-based boost controller you can custom tune the whole boost curve, not just set a target and "hope for the best". This can give you much more usable power under the curve.

Any links to the pill where I could purchase it? Thanks again.
If you would like to just replace the factory pill with the upgraded pill you can get it here:

We should have the full "swap" boost assembly available soon.
