I had the same issue but it was fuel delivery on my Turbo Busa. Double & triple check everything with the fuel pump. Did you transfer the factory fuel pump housing o-ring and add 2 more than came with the pump? Idle fuel pressure maybe fine or manageable with a missing o-ring but when its time to give if gas the pig will kick and spit.

First thing I always tell people to check is whether or not the Tial Q BOV is opening up at idle or in high vacuum situations. If it is opening, that is most likely your issue as it causes turbulence in the air flow across the MAF sensor which causes large swings in fuel.

Remember it is just a basemap. You need to get it properly tuned.

That is correct, we leave our maps on the conservative side and recommend a tune to dial her in properly.

The best was you I could describe MAF turbulance on a FBM turbo car is that it would feel like someone was *lightly* tapping on and off the brakes repeatedly.

If you think it may be turbulance and not a fuelling issue the quick look places are the long silicone pipin behind the pass headlamp (is it pinched) On the BRZ they reccomend you unplug the clips that hold the wiring but in the end it still ends up with a slight kink. The second place to check is a the MAF sensor. Unplug and clean it. It is very easy to get a bit of oil/blow by from a fresh install on it (since it is on the underside of the charge piping.) Also tripple check the O-ring around the MAF sensor. You may want to use a bit of RTV to ensure it is 100% sealed around it.

If you give it gas and hold the revs at 1500 or 2k is it pretty smooth? Vac leak?

Make sure you have all the vaccuum lines correctly installed. IMO it was easier to run all the lines without the EBCS to make sure the car was running well. Then add the EBCS and tune for it. Start simple and then add to her.

held it at 1500-2000 and it goes down about 500-750rpm then back up
i removed my EBCS and only have the WG/BOV connected to vacuum and
still idles rough as if its misfiring.

i contacted delicious and they told me to check the direct injector black metal covers to make sure its making ground and i removed and check them both and it still does it.

anyone got any idea of what it is?


heres a log of my
rough idle and i stalled right at the end..

Hey guys. Here are the pics you guys wanted to see.

Sorry it took so long. I took them but tapatalk had issues with my image resolution so I had to do it on a computer.
@mashal @King Tut


Catch can with filter to vent to atmosphere.


Weather stripping to make the seal work better


It's hard to see, but just past the latch and under the metal bracket, you can see a layer there. It's some sort of weather proof material my dad had in his garage. It worked perfect. I'll try to find exactly what it was I used. But it is essentially another layer that makes a seal to stop water from going past the holes underneath the metal bracket.


Rust forming around mounting holes. This car has never seen salt from the winter.


More rust
