Well.... with the exception of force induction... almost every performance mod on the 1.5L engine will make very little improvements. The important thing is if the gadget actually works and actually gives some improvement and per your statement it looks like there were some gains...

Usually it will require quite a few extra hp's to lower 1/4mile times by half a second...

Also, did the test car had any other modifications? Or was it a stock car?

Messing around with the fuel ratio usually will have better results on cars with Free flowing intakes and exhausts.

So if this thingy can give an extra 10-12 hp to a modded car... perhaps it would worth looking at it.

After all... people have paid $400 for an axle back...


Another thing that comes to my mind is that this is actually a "TOM's" gadget... and if they don't know their stuff when it comes to Toyotas... who does?
