I got my Greddy profec B spec 2 installed today and noticed they did not install the Filter that goes between the pressure source and the EBC control unit running to the inside of the car. I was wondering how important this piece is. The manual says this MUST be installed. But then why didn't they install it? I was wondering if any of you left it off or not? I could always just cut the vac line and put it in there. Also the manual says you must put it in the right way but when u look at it there is no indication of which way is right....

I have a K&N Cone filter and 3" cat back does anyone with similar mods have some good settings? I am looking for some lo and hi settings.

MY hi
Gain 20%
Start 17 psi
Boost 50%
warning 20.5
Limmiter set to 40%

These seem to hold 19 ish....

 

might want to change start to 13 and warning to 22, but with no fuel control just be careful
good unit though holds boost well

 

Nevermind I just installed it took a total of 5 min. LOL

 

How about max boost setting? I have been reading on here about the most boost you can run with no AFC on a fairly stock evo except K&N cone filter and 3" cat back exhaust. I have heard anywhere from 19-22 psi? Can I get some opinions on that?

Thanks
