Well, I reckon if they see an aftermarket header, it's obvious you'd have a tune...and they can tell if they look. So if a tune voids warranty, you maybe best staying off a header (as it's a very telling sign).

p.s. I've had the car in for warranty since the whole thing, when I hit a curb. Nobody cared about the aftermarket parts nor the tune. I've even told them not to mess with the ECU in any case, as it has a special tune on.

Yeah that's why I thought I'd chat to them about it before doing anything. And also why I thought a tune alone would be ok if they are super tight about warrantys

I think it's only an issue if the dealer wants to be a dick about it and try and weasel their way out of some warranty work, the majority of the time it's probably a non issue but you hear the odd story where they can really be pricks.

Dex I was simply referring to flashing a tune on a completely stock car with the stock header. You are looking at a minimum of $4-500 dollars for at best a 3-4kw power increase and having the motor run a bit better all round. That's not a big sum of money in car terms but I guess what I meant is it's up to the individual whether they think that is worth it or not. It's not like modern turbo cars where you can flash a tune and get big performance gains.

Yeah I'm aware there wouldn't be a lot of extra power with it stock. The stock tune as it is, is different to previous 86/BRZ's, so I'm not sure if with the combination of new bits on the car and a different tune out of the box means flashing it will be more or less beneficial. Rather than a peak power gain, i'd be actually more happy to smooth out the torque dip a bit more. Once you get out the other side and over around 5k, the car goes reasonably well. You just spend a lot of time hitting the bottom of that dip during day to day driving. If I don't grab new headers I could always run it on E85 with a tune.

Sorry, I'm an idiot. That was not warranty, it was insurance I had. Anyway "something official" :)

At least with the pre 2017 motors the only way to get rid of the torque dip is with a UEL header, the only EL header that has been shown to remove it is the ACE one that ysu has. I'm not an expert on all of this stuff though, maybe the Stage 1 tune does help reduce the torque dip somewhat but from how I understand it it's more like a tweak rather than significantly changing the way the motor behaves.

I'm pretty sure if there was a way with stock headers, Toyota or Subaru would have found it by now, and it would be on the 2017 car.

There's a group buy going on at the Vic 86/BRZ club that I've joined. How difficult is it to fit this expensive piece of plastic?

Doesn't look like it's that difficult although I haven't watched the whole vid. I would question if you really need one though, sounds like it's only a problem on longish high g left hand turns when using e85 and/or forced induction. Seems like you would also need upgraded suspension and tyres to reach the type of g's required.

I've heard about a fuel starvation issue earlier (not sure if it's the same) that was only affecting FI cars on slicks.

It will affect cars on e85 and above on high g left hand turns. More so if an aftermarket pump is fitted.
The flap is aluminium and for me is worth every cent as it heaps cheaper than a $1000+ surge tank setup. We've got some almost here and should come in at a great price.

Sounds good. So on E85 is already that much thirstier, huh?
If I may ask;
What's the mileage on E85 on the track? (I've got around 22L/100km on ron98 - which is awesome compared to the supercharged lotus I met at EC, hehe.)
And what G's you guys are pulling in those left handers? (those who have this issue)
