As Craig said,,
Not going to prove anything to any body. I use it because I notice a difference in economy (yes reduced consumption on the Hwy, Just drove Albury to Sydney door to door for 10L/100km). The low speed drivability is something that has to be felt as it can not be shown. And intake temps, I run an informeter on my car and can see how quickly I can bring down the intake temps when driving.
Don't believe it, don't do it.
