So I just installed my boost gauge........and was wondering what the stock boost from the factory is? Next I'm going to install my MBC and I just want to make sure that I set it to stockish levels. But I also want to make sure that my current readings are correct.

Any help appreciated!!!

And Thanks to those who helped with my boost gauge!!

 

What year evo do you have?

^^^Good Read answers all your questions^^^

 

2008 gsr

 

Mine was 18psi stock tapering to 14-15 in the upper rpm range.

 

Thanks but I dont think it has the info that i need...I have an 08 GSR

 

Yeah that seems about right.....seems kinda low tho...considering what past evos have put out stock

I'll check it again tonight when I go to work.

Do you have an mbc? If so did you set it higher? or left it near stockish levels......i currently have no mods.

 

Other people have told me mine was low stock, but my snap-on scantool doesn't lie so I guess my car wasn't made on a Wednesday

I do have a Mbc, I set it at 24psi (65* weather) and it tapers to 19. My afr's are still rich even with my other mods.
