When you say pulled the rear o2, are you talking about actually unplugging/removing them, or just shutting off the error code?

Thank you all, I'm sure we will get it figured out. The shop owners text last night seemed confident that they know what the problem was, I hope he's correct. Top, good luck on your new adventure. I usually go to Minneapolis once a year for work, I've always enjoyed it in the summer. They sent me one time in the winter, that crap isn't ever happening again!

Top and Evohunter, when we first started the car with the blue spring in the BOV it stayed open at idle, did yours do that? The tuner is remotely tuning the car so looking at the log he said " it's seems like we have a massive boost leak?". When we told him it was open he had us use the other spring so it would stay closed, What does your BOV do at idle? Even with a low idle that thing is moving a lot of air!

You can just unplug them if you want but I completely removed them plugged the bung.

It should be open all the way at idle, make sure they mounted the MAFS the right way, and not backwards. but at idle your car should run on atmospheric pressure, hense the BPV completely opened at idle.

I hope they dumped the Original stillen tune and started from scratch aswell.

They did, we are using ecutech this time.

Thanks man, I will check all of that on Monday.

Evohunter/ top, did you start adjusting the BOV from its softest ( unscrewed) or hardest ( all the way tight)? I think it's the first but looking for as much info as I can get before Monday.

You have to have it wide open at idle. That bypasses all that air or your motor would need to idle with a ton of air being forced into it. It should idle with 17hg of vac.

I watched mine to make sure it slammed shut upon accell. Your line to it will be forcing down on the spring once u hit boost so it equals out the boost it's getting from the charge pipe.

With the blue keep it unscrewed as possible but your still going to get some turkey ****.

Thank you both! I couldn't and wouldn't have done this without your help.

I didn't have time to spend at the shop today but I don't think they have figured out the base tune yet. So frustrating.

That sucks. Are you doing the speed density tuning?

They are now.

Still getting nowhere fast, I don't get it. Tops who tuned your car?

Dang man is it still the idle issues or something else?

Same thing, they cant get the car a decent base map. I have lost faith in the tuner, the shop has reach out to Specialty Z at my request to see if we can get them involved.

What is your bpv doing? Are you using your mafs?
Call me. 701 306 1779

I set the BOV like you told me but the tuner had them install a spring that kept it closed at idle. When I told him it was wrong he didn't want to hear is and told me I didn't know what I was talking about. We are going are own ways, I'm over him. If you don't mind I may have the shop call you tomorrow? We have tried the MAFs and SD tuning but he can't get it to even idle.

It has to be open. That guy has no idea. No wonder he can't tune it. He doesn't even know how a centri setup works.

Are your mafs in the right direction? I had screwed that up my first go. It wouldn't idle at all. Check that out for me.

We talked about that tonight and they are checking it tomorrow. We looked at it together but I was checking it against the Stillen y pipe but I realize now it should be the opposite.

I bet you that's the problem! Let me know. You can't just flip them though, but you can mod the maf housing to get it to work.

What did you need to mod?

Specialty Z is going to tune the car. They want a new 3 bar MAP sensor installed so we ordered it today. I couldn't be happier to have them involved.

Remotely?

Yes

Good. Seb should be able to get things straight for you.

When the kit first was installed I took it to a tuner that I really like but the car kept going into limp mode while coasting. That tuner called Seb and he said make sure they installed the piece that blocks the filter. They had not and that solved it, so I have faith in him already.

Are you now 100% sure the maf housing conductor slot faces air flow?

First installed like oem install? That won't be a problem Anymore since your blowthru vs pull.

I haven't looked but make sure the depth of mafs and angle are legit. Also check for funk or gunk on the sensor conductors. If your going map I guess this is a moot point.

Make sure your fprs is ranged also. But if your old tuner couldn't get that right then....

I had to much going on at work today to go by the shop so I don't know about the MAFs yet. I will try to go by tomorrow if I can get away. The MAP will be here tomorrow so maybe we can get her to idle. The car has been stressing me out but knowing it's being tuned right as made me a lot less worried. I can't wait to drive her again!

Snap me a pic of your maf sit rep if u want.

Thinking more about this...

Something has to be way, WAY off for this thing to not idle. It's crazy your trying to base map it with issues much less WOT tuning.

Check things like your vvel harness clips, plug clips, throttle bodies, etc...

If everything is solid, it will idle fine with the tune you had even.

If I can get away from work today I will take pictures. Strange thing is that the tune that was on it the car idled, it was pig rich but it idled. That is when I started questioning the tuner, every base map he tried was never as good as the uprev tune.

Hmmmm..... Tuner must suck.

Thankfully I'm done with him!The MAP should be here today so we can start trying to tune it again.

Can you add more input on the correct MAF housing conductor slot? I thought there was only one way to do it. Please clarify as I am now paranoid I did it wrong. I just put them in and tighten them down in the BP kit the same way I took them out. Pics, drawing, or pop up book style would greatly appreciated.

They only fit one way but because my pipes are custom the mounts could be welded on backwards.

Yup. I used the stillen intake y tube but inverted it so my mafs were facing the wrong way till I modded the housings. Your gtg.

first thing first, we need a picture of your mafs in those pipes.

If those are good, Smoke test her. I wouldn't be surprised if you have a manifold leak or tb leak or something.

Im leaning towards the mafs being mounted backwards.

with your kit the mafs are mounted properly and can only go in one way.
cant mess it up. I have a feeling they replicated the stillen intake pipe which wont work with the air to air.

un screw the 2 screws in the maf, pull one out, and take a picture the same way it came out. this will tell me and top if there right.

Now that we are speed density tuning does it mater?
