Ok I have been asking around town and still have not gotten a straight answer. I was thinking of getting a Boost controller. Is it even worth getting one with my setup or not? Someone please help me out here.

Here is my setup so tell me what y'all think.
I have the stock turbo
injen cai
turboxs rfl bov
thermal cat back exhaust
Boost gauge
Egt gauge which I nneed to get the probe for so I can get it working.

 

mbc is cheap, but i recommend you to get the Electronic Boost Controller like Blitz SBC-ID or Greddy Profec e-01

 

Get rid of the CAI. It will lean out your air/fuel ratio. Not good.

 

I was wondering what the difference between an EBC was and MBC was? Also kinda off topic but how much would a turbo back help? catback? axelback? if I were to put it on all stock on a wrx.

 

the difference between EBC and MBC is the accuracy, the way you set the psi boost, and the price

MBC - good part :
it's cheap ($50 less)
easy installation
-bad part :
boost psi is not that accurate
you have to set the boost manually, and then drive your car and
test if on 4th gear is 16psi
u will need boost gauge

EBC - good part :
easy to adjust the boost
graphical interface (looks cool)
-bad part :
hard to install (you'll need pro to do it for you and it's not cheap)
expensive

but i were you, i will buy the EBC
i just don't have the money to buy EBC

all i know about turboback is that you can gain 30-40 hp with the unichip / utec, i might be wrong though

 

thanks man! What do you think the gains would be with just an up pipe and a turboback, just these mods and completely stock?
