Ok, so along with my parts suggestion thread, I am looking to upgrade the MAP Sensor to a 3 bar or that Omni 4 bar plug/play one. I have been looking and looking, and understand a little about the "Closed boost" system on the evo. If I want to run higher boost(boost controller), and monitor boost better(MAP SENSOR), will the stock boost control unit be able to hold the boost better with the MAP sensor. Therefor do I need to upgarde the boost controller?

Some of the threads I read about this subject are kinda confusing. Is the stock evo boost control up to the challenge of higher boost with a better sensor, or is it still needed to do both upgrades, one, one over the other?

Thanks in advance if this has been covered a billian times. Thank you for taking the time, and please post a sticky to this info if there is one.

Thanks in advance.

 

Is the map sensor the same as the boost solinoid?

 

Ok....hmmmm.....

No one understands how the MAP sensor and the Boost Solenioid work together?

When I upgrade the Boost Controller, does it come with a new solenoid. In essence am I raplacing the Stock Solenoid with the new boost controller?

Has anyone worked with the 3 Bar or 4 Bar units, that can tell me anything else they did or di not mod when upgrading that unit. I am only primarly speaking about the boost system and the control of the turbo. Don't need to know that you upgraded cams, or other parts.

Has anyone bought the the 3 bar or 4 bar, and left everthing else stock, and had succes with higher boost and control?

Thanks in advance again.
