See, that was way more clear. There is a language problem here. Yes, you can vent instead of recirculate. You just need to use a foge004 or HKS ssqv

 

what about adjusting the fuel and air mixture? Does this mod take into considerations everything that goes into an internal combustion engine or does it just boost pressure? How does this mod get the fuel injectors to spit out more? I'd love to try this, but if all it does is boost pressure, I'll have to past..

 

Newbie question... is is cool to just install the diode, and will you still see performance improvements?

Thanks, Sebas

 

Just installing a diode wont do anything for you.

The increase in flow from the maf and the o2 will allow the ecu to control the a/f to a point. This is why we limit it to 17psi on stock fueling and no other changes. I have taken it a step further with a stroked 1.8 to 2.0 and you can see my results in my sig. This is with a perfect 12:1 a/f from peak boost on.

 

17 psi limit? That's a shitload.

 

Its really not. most people with chips run in the 20-22psi range.

 

so ive done the diode mod and i couldnt be happier. i do however have some questions. right now im set at about 15-16 psi, and around 3-4K rpms theres a little shutter and the powers not strong. above 4k it feels nice whats going on?? i have 4 new coilpacks and plugs (ngk bk7es i believe). do i need to add fueling or timing??

you should hopefully of gapped the plugs down to .028.

 

yes i did gap them down. it seems to be getting better. i suppose it just adjusting

If you still have problems, you can also look into bypassing the n115 and n249 underneith the intake manifold. This will make it so they cant open the dv to release pressure and then move the boost source to their vac line. This will give you a smoother transition into boost.
