Loss of power

[shadowx]

gen3 cars are known for having weird idle characteristics. According to Lund its something in the Ford calibration that causes the phasers to go to 0 randomly.

Does it lower the hp significantly too?

Also, I have the closed steeda intake with the insert out

Who’s tune ?
You have this CAI installed ?

CAI and headers is not FBO. Check your CAI and make sure its tight on throttle body and at the filter. A loose filter clamp can and will stall your car, it also explains the uneven idle.

yes ik lund
here the video though:

You know more about this stuff than me so let me know what you think

No it won't cause any power loss, it's just an idle characteristic.

Not saying that your idle issue is this or that your idle issue isn't indicative of something else being wrong.

You should post some logs so we can look through them and see if anything jumps out. Would be good to post old logs of when the car was running good if you have those too.

I did not know this. Maybe that’s why my car idles like crap on the factory tune.

It's not supposed to. If the idle is wonky it's usually because the phasers can't hold lock on their target, either because of the solenoids or the phasers themselves. I could maybe see the oil pressure bypass exacerbating a borderline issue, but anyone who says that's normal or expected behavior is smoking crack.

Now if you're talking about the idle being "chunky" but consistent, then yes that's normal as far as I can tell.

If this is a tune issue from Ford all cars would do it.

I'll hold off judgment.

Overseas tuner. Yes that's my CAI.

I will definitely try to do some logs soon and post them here.

The stock guy who gapped me is my friend and he may need to check his vct. He got the code P0012 once and his idle or when he stops is doing this weird idle characteristic. He got it worse than mine. So I guess it doesn't affect the power.

PM sent.
Off the cuff I believe you’re experiencing MAF air flow turbulence issues.
Use the M6G search feature for the CAI being used to gain more insight.

Are yo using the insert for that CAI?

If not that item responds well to an added air straighter. Honey comb or sometimes just adding a screen helps a ton.

The insert is out.

Add an air straighter. Where the tube slips together before the MAF sensor, get some window screen and wrap it around the tube so as for it to be flat across the tube opening. This should help. If it does buy or make a honey comb insert.
