OK This is my opinion of this device. I have a lot of years of tuning cars behind me and I say that as far as performance goes, this thing is BS. There is only so much you can do about the volumetric efficiency of an engine, BEFORE the valves, combustion chamber and exhaust. A supercharger is an improvement, but swirling the air around isn't going to do much to improve on that. Save your money. (rolls eyes and shakes head)
Funny that there is ZERO data about any kind of performance improvement on tonemonday.com
I want to see some HP numbers before and after install.
