Thank you all.

Given that the SS version is on BO I ordered the coated version though a FI is not intended now or in the future.

The reason that I'm asking about the tunes is in part due to the fact that the extra top end power that they show will require more fuel and the AFR calibration may/will have to change. Or can this ECU learn and deliver more fuel within a tolerance margin?

If tuning is mandatory, and since at this point OFT is reported to not be actively supporting their product, I'm not willing to undergo the expense and the complications.

Thanks again.

Tuning is partially "mandatory".
With stock tune gains from aftermarket header will be less, and one will need to clear catalisator readiness CELs from time to time for cruise control to work. Otherwise car is normally driveable.
I wouldn't completely write off OFT though. Imho it's nice for DIYers due non locked tunes and lot of good tuning information by community available, and there are other competent tuners that can help you with, eg. steve99 and wayno, for reasonable cost, even if you are wishing for more then OTS tunes and want to deal with someone else but Shiv for fine tailoring your tune.

Thank you churchx, I had no idea. This makes me feel a lot more comfortable going forward.

Scala: keep in mind, if you are after custom tune performed on dyno with some local tuner ship and or have more then basic bolton mods, but eg. also forced induction, then imho going ecutek route is better, as most tuning shops use it for twins.

Appreciate that, thank you.
I will only be installing the catted UEL by FT86 Speed Factory and nothing else. The guys at SF tell me that I will not need a tune as long as I install no other parts but I prefer to tune to avoid any trouble with the AFR and also to take full advantage of the 93 RON.

If you haven't yet bought that catted UEL, i'd rethink your plan. As i've mentioned, catted ft86sf is not sure way for CELs to not appear with stock tune, so why bother? If you'll get ecu tuned anyway and cat readiness checks can be disabled in custom aftermarket tune, why not go for catless header for noticeably more gains & cheaper price of header?
Those guys are right that car will be usable with stock tune (apart from possible need to clear CEL code at some occasions), and i guess gains of less torque dip and UEL burble-ish sound will be there with stock tune too .. but then again overall gains will only be very slight, yet catted headers cost more then catless ones.
I'd rather get ecu tuned no matter if with or without aftermarket header. Except of course if with ecutek, then only after all planned mods installed, to save on tuning.

Thanks for the heads-up.
Catted for the noise reason. I've heard both and the catless is much too loud for me. Same reason for stopping at the header and not going beyond.
UEL and catted because of the pulse rumble which I am used to and I like on my STI and because I'm hoping for a lessening of the torque dip in the mid-range.

CELs is something I'm used to and anyway by now I'm very close to deciding in favor of the OFT just to be safe with the AFR.

If everything seems on the up and up, that strikes me as an awesome price. I have one in my attic with 13,488 miles on it and I wouldn't even consider selling it for that little.

Thanks, so <20k miles is considered pretty new? Do you know how much is the drop just from having it mounted?

It doesn't matter how many miles lol
Used is used. Sell at half price as usual or sell at half price with extra $100 on top or just a tad lower than half. If the price doesn't match anyof those 3 options, it aint worth it.

I doubt there is a standard drop in value just for having it mounted. It's used; it's worth less. Like anything, the price is what the market will bear.

Got this header installed last thursday and Iīm quite happy with it. To me it mostly sounds stock (the rest of the exhaust is still stock), but the torque dip is definitely gone. No tune and no CEL so far. I donīt get why it doesnīt come like this from factory. I think the extra pull in the 3k-4.5k range will help a lot as a daily. I got it used for 400$ so I couldnīt be hapier.
