It's the same as the non vvti diagram for the sequential operation you can find in the FAQ section.

 

Looks like someone's fiddled with your Sequential operation.

 

From memory their should be a pipe from top left to bottom left and one from top right to bottom right.

if that is on the exhaust manifold side, then the EGV valve will never open up in that configuration, unless its been hard wired.

 

Im guessing it would also disable the second turbo, been awhile since i looked at the diagrams..

2nd turbo is working now.. WOO HOO!

 

now for some reason i'm running super rich. My wideband says it's below 10a/f. Only after a 40-50mile drive. Car starts to bog down because of too much fuel.

 

I'm still running stock ECU. Anybody have any idea what i should check?

everything is stock.

i do not have an aftermarket FPR.

 

it's at 10.5 on wot when it's running correctly.

 

When it bogs, my wideband says RICH (anything below 10.0)
