Okay, before I get flamed let me say that I have NEVER been a fan of any fuel additive
. However, I recently witnessed two tunes that made a good bit more power after adding Ethos.
The first car was a GTR which made 570whp before Ethos, and 596whp after. The second car was a 2010 STi which made 306whp before, and 320whp afterwards.
These tunes have me thinking, but based on the information I found on the web it looks like every other BS fuel additive out there.
Any of you guys run it, or have witnessed dyno runs after adding it?
