can someone help me out and post up a pic of the vaccum diagram for and 05 evo mr i looked in the search and i am finding just the 8. My problem is that i keep getting 12 pounds of boost but when i take off my boost gauge and dont interrupt the line i feel more power. I need the find the stock vacuum diagram for the mr. Please help. Thanks

 

Bump

 

WHY ARE YOU POSTING THIS HERE? THIS IS THE EVO X GENERAL SECTION. And your answer probably lies in the fact that you don't have the boost guage installed correctly and it's leaking, or you've got a boost leak somewhere else. Make a boost leak test kit, cobb tuning has a whole article with step by step instructions on what to do and where to look for leaks on their website.

 

i did leak tests i know the problem just need to get the vacuum diagram of an mr to put back my lines to stock

 

First of all, vacuum lines are the same on ALL 8-9 Evos...MR or not.
"Noob" MR owners always think this way.

Anyway, is the boost gauge tapped on the left side of the intake manifold? 12psi is the wastegate pressure.

 

By definition, all '05 MR's are VIII's. Where did you tap into for your boost gauge reference source?

 

I know all 05 mr's are 8 but the mr comes with the factory gauges am i am trying to find where that is connected too does anyone have any pics of the vacuum diagram.

 

My car has a vacuum hose diagram stuck on the underside of the hood. I imagine all Evos came with one.

 

thanks barneyb i didnt even thought of looking there.
