Engine carbon cleaned

[Kdyjas]

Hey folks has anyone ever had there engine carbon cleaned ? Thinking bout getting my blob sti done,, any thoughts ??

I was looking into Terraclean before my map. Searching around people said it improved the car but did not last long. I also asked Racedynamix and they said it is not worth the bother. If your failing Emissions it might be worth it otherwise if it ain't broke, dont fix it for me. Talk to terraclean sales and they will tell you that they get best gains from boxers and they run dirty, lol $$$$$$$$$

Av no cats so don’t worry about emissions lol it’s only 60 pound to get done and seen a lot of good reviews but am still not convinced lol
