Total BS.
I see it helping a little, but why the hell not run it all the time?
They say it only works at WOT???
What about all the turbos & superchargers? They work al the time (well above some RPM).
Ahh, they are afraid of damaging it.
Hummm, why would you want something that is so easely damadged in the first place?
Personaly i run at WOT a lot & with my driving (based on what they are saying) it would be gone in less than a months.
I just hate when some joke-offs put some BS product & sel it to people who don't know better.
Sorry for my ramblings, just being an ex-riceboy it realy turns me inside out when people are BSing that much.
