exactly.. Its like Viagra to the car.. lol

 

so that means i have to get it tuned? i cant just turn the boost down?

 

just run around 19-20 psi and you should be alright.....watch out for the winter though....the colder it gets the highers you're boost will spike. I had this issue myself hitting the boost cut on very cold days.

Depending on the amount of mods you get and the boost you are running it might be a good idea to get a Walboro 255 upgraded fuel pump...this with ensure that you are not leaning out your fuel mixture too much at higher RPMs. Goodluck!

 

Turning the MBC down is safer than turning it up if you don't know what's going on with the AF ratio. An AF gauge is a good way to see what's up. Lean is bad. Very bad.

well i really thank you guys for the help

 

not a problem....just keep reading these forums and what not.....you'll be amazed how fast things start making sense and tie together....this forum is reall great....i browse through it every day

 

Ok I'll be nice. Meet some import guys around you and know their stuff. Listen and learn as much as you can.

 

I was nice from the beginning.

 

get the fuel pump at **************** D.

 

i don't have a A/F ratio gauge and i'm running a TI catback and a GFB bov do you think i might be running lean at all in any part of the RPM's??

can you guys give me some info about this

 

It is possible that you could be running lean.

There's a few ways to deal with that. The SAFC 2 is one good tool for
adjusting your a/f ratios, with a wide band sensor installed, a datalogger
you can do a lot.

There's tons of information about electronic engine management. The more
you can gain understanding the better your Evo will run.

I'm learning myself... and learn more as time goes on.
This forum is a library of information.

 

No.

 

thanks spec'd

does anyone else have the same set up as me that was thinking the same thing?

 

go get a dyno for sure with tail snifer afr readin...

stock cat would make it... lean? or rich? on the reading? i forgot.

 

A cat-back and a BOV is not a setup. You are not running lean. Evos run crazy rich above 5k rpm under boost.
