No difference at all?

 

I have a forge... it's nice, but still tapers. Good if you get tuned to run 22-23 psi which should be ok (as long as your tuner says its ok!).

 

Neither! Go with Electronic Boost Controller FTW! You'll end up getting one sooner or later. =)

 

Ok I will try hard not to be harsh....The stock taper is designed in and can easily be elimated (e.g. stock redline boost is less than 15psi and I am holding more than 19.5psi)...

You can modify your ECU so that you can boost much more than 21 peak and significantly reduce your taper...Look at my signtaure -- I am currently hitting 24.5 psi (peak) tapering to just a tad over 19.5psi at 7000+ rpm. You can control the boost taper MUCH better with an EBC or ECU/BCS setup than an MBC.

So, given that you only want a boost of 21psi (peak), I would HIGHLY recommend using the ECU/BCS setup and contacting a vendor like Jestr for the tune / ECU modification.

Good luck...

 

Look, I don't want you to be "harsh" either :-). I have seen your signature, and I recognize that you must have a plethora of knowledge about these cars, and I thank you for your responses. From what I have read, the stock hoses prevent the ecu from being capable of giving over 21 pounds of boost. What if I removed the pills from the hoses? Would that help?

From what I've read, I might have to disagree with your conclusion that I will not get more boost from an MBC set at 21psi, than I currently get with my stock boost setup. I could/may be wrong, I know that there is still some tapering with an MBC, but I'm not sure that it can even be close to stock tapering.

I am going to get a flash eventually,

How much boost can an Evo IX handle with a completely stock setup?

 

I can tell you this originally when my car was flashed from DYNOFLASH it was boosting to 22-23psi and holding......and the gauge was correct. So yes with removal of the pill(which is usually needed for the extra 2psi with most basic flashes) you can hold over 21psi. Im just trying to throw my 2 cents in to help hope it didnt confuse you.

 

I vote Forge, but clearly, I'm biased.

A boost controller is not the only thing related to taper. Supporting modifications for the desired boost level (including proper tuning) as well as a properly setup wastegate actuator (stock or aftermarket) will also affect taper.

Any "issues" are always covered under our lifetime warranty. There is no excuse for someone not contacting us with any problems and not letting us resolve them.

 

To hit the 21+ peak psi (whether you want to run 21 psi or 30psi), you will need to modify the pills...Evo_Kid did a nice write up in the ECUFlash section.

The stock ECU/BCS can do a perfectly fine job of managing your boost and controlling taper. If all you want is 21 psi peak, then you could easily control taper such that you are at ~20 psi at redline (beyond that you are going out of the turbos range).

For most street applications (on pump gas), 22 - 24 psi seems like the general consensus...That said, there are other things you will need to do: t clamps - to prevent your hoses from popping off, a new ECU map, and maybe a fuel pump although I don't think so based on your desired boost.

 

+1

I went from a Forge MBC to an electronic one and couldn't be happier.

 

I thought boost controllers were to help with the tapering? I peak at 1.3 bar and taper down to 1.0.. geting a boost controller should let it taper to 1.2ish instead right?

 

I went from a crappy turbo xs mbc to the forge and absolutly love it.

 

This was what I have been told by people that I consider to be "experts", but It seems like a few people in this thread think otherwise...

 

Lets say I'm going to set my MBC so I get around 22psi of peak boost. Should I be removing the pill before installing an MBC?

Thank you

 

if you look at the STOCK set up, it bleeds from turbo nipple to intake. Using an EBC or MBC you not bleeding at all. The total flow is stopped until your "set boost" of your controller, where then the spring and ball lets air flow from turbo nipple to wastegate.
and boost control cant increase boost coming from the turbo it only can increase the range where boost is able to peak at, if the turbo allows such boost in the first place, i.e. you not going to hit 22 psi in 1st gear just using a MBC, however your spoil up will increase "very small" over the stock bleed through one.
MBC or EBC is cool because you dont have to take out your laptop to adjust boost, you just twist it a few times and done.
If you plan on leaving your boost set and never touch it and dont mind a small lag in spoil up time over using a MBC, then Stock ECU is the way to go. Saves money and hassle of connecting the mbc in the first place
BUT, if you plan on increasing boost over stock, or wanna increase your spoil up as much as possible and plan on chaning boost often, an mbc is the way to go.
