Doh! I stand corrected, sorry OP

I have the same car, I would say NONE.

Fyi, my service advisor says headers will not void the powertrain warranty. A tune for them will, but it's not absolutely necessary to tune for headers. You'll still pick up good power but will have to live with the CEL. I've had it to the dealer twice since the headers and had no problems with warranty work. Probably best to check with your dealership first like I did, but so far so good.

It is necessary to tune for headers on these cars...the throttle will close some @ wot if you don't.

Why is that? Not sarcastic, just wondering why headers causes that to happen.

Yeah I have to admit the SS has a way of making higher speeds feel innocent. I mean cruising at 80 MPH unless you are checking the speedo you wouldn’t believe you were doing more than 65.

My other cars (G37, LS3 4th Gen, Toyota Prius) feel like I’m moving at that speed.

These E92 ECU's are torque based. So headers or any significant mod will cause the engine to exceed the torque limits programmed in the ECU. If you make more torque then you have to raise the torque limits or the throttle will close to stay under that limit. The only mods that can be done and not bump into these torque limits is a CAI and ported stock IM/TB.

Do we know what the torque limit is? I'm now wondering if any bolt on (IM, CAI, PTB) will actually increase torque if it causes this reaction.

Also OP, sorry to derail the post.

[KingLT1]

Yes there there is enough room for those mods without bumping into the torque limit. It's been documented. Just search Pray Performance and start reading up on all his testing over the years.

Necessary to see full hp benefit sure, but if you're still under warranty, want some extra sound and a few extra ponies it's fine to run without a tune was my point. When the warranty is up, tune away and pick up even more. I see a lot of posts here where people think the car will run terribly (without a tune) or the warranty will be immediately voided when you bolt them on and that's just not the case.

It will run but it won't pick up any power. I just explained why.

If you’re not going to tune, you’re better off not running headers at all IMO.

King’s description of the E92/E92A is spot on, of course.

The ECU uses airflow to predict/command/calculate/limit torque. So, changes in airflow profile means the car can now bump up against the commanded max torque and/or its peak torque limit. And it’s not just a limit, the computer commands torque values that dictate how the engine runs, so you can’t just “max out” all the limiters. Getting too close to those limits means spark cut or throttle blade closure to keep calculated torque to what the ECU is expecting. So, any significant mod will need a tune to keep the car running and performing properly.
