Is it safe...

To run a fuel system cleaner through this engine? The manual says not to run any additives, but I've got about 39k mi on mine and it feels a bit sluggish.

I have run Techron through my wifes 6i a few times. No problems.

Is it safe through the DISI turbo though? I don't want to gunk anything up.
