Has anyone had this done on their car? I have an MY97 with about 75k on the clock. It's running okay, but was wondering if this exercise made any real, noticeable difference in performance etc?

Are there any risks involved with the process - do Subaru recommend it or have anything to say about it? Or do they perform a similar service at their garages?

 

Don't know about Scoobies, but I had the injectors ultrasonically cleaned and flow tested on my GT4 at 100k miles. Made quite a big difference. Mainly the car drove much smoother and the idle was much more stable. That was done at Powerstation but I guess TSL also have a cleaner and flow system as well ?

Cheers
