Temporary pipe replacement and tune

[Gleekzorp]

Hi,

I've got TOR pipes, Ram Air filter and some cross pipes on my 2016 Roadster, and a tune to match that. Now I'm thinking about a trip through some countries where they are not very fond of those loud TORs.
If I temporarily swap the TORs for the stock exhausts and do the 12 minutes tune, will that be enough for a decent setup, of do I need to revert to the stock tune?
(or is there a special tune for RamAir, cross pipes and stock exhausts?)

Thanks!

You will still need to keep the existing tune to take account of the Ramair (otherwise you will be running too lean)
I would say that you will be fine with the 12 minute tune after putting the stock pipes back on.

The 12 minute tune only works at very low rpm (low gas flows). R3 sensor is a narrow band not wide band. WBO2 works across entire rev range. All this is really/effectively useful for is a stable idle.

However tors to std muffler? You'll probably just run a little rich is all. Not an issue and any plug carb buildup will clear by giving it the hand occasionally. I wouldn't worry about it.
