So I recently went binging, and got the standard bolt-ons for my 2010 GSR.

-ETS Intake
-Test Pipe
-Cat-Back Exhaust
-Cobb Accessport

I am not looking to go extensively beyond this, just want to get a little more zip and a little more sound out of it. I am relatively new to modding Evos, but I come from a thick DSM background (where everything is manual). The EMBC and controlling boost in general on the Evos confuses me. Do I need an EMBC installed to increase boost and get the full power from my Cobb tune, or does the Accessport do that?

 

Bump. Any help out there?

 

The cobb tuner will give you a good baseline map that will be ok. A protune later on will allow you to take full advantage of your mods. But no you dont need and EBC. If you do get one make sure you get a tune right away otherwise you will most likely overboost. But the cobb tuner and the mods you listed will be a noticable difference!

 

What benefit would the Grimmspeed EMBC provide then, in this case?

 

IMO, it provides a more smooth boost curve.
The 3 Port solenoid will keep your boost more consistent and keep any boost spikes to a minimum.

I had cobb ap before, with stock setup running with OTS map, it was able to spike up to 27-28 psi.
