Hi Ron,
First of all - every, and I mean EVERY, motorhead should be considering your modification. The increase in throttle response is wonderful.
On my 2010 Prius I am getting wonderful power increases - read that as significant power improvement! My mileage is also going up, but then I'm using the power. It almost feels like there is a momentum / inertial change in how the car feels during acceleration - very ineteresting.
But here's the interesting part : I did finally find the PCV Valve on the new model Prius, it's UNDER THE VALVE COVER. The only hose I have access to is the hose leading from the PCV Valve to the air intake. This sits right on top of the engine so it is easy to get to. ( I addressed that hose appropriately ) And my power went up again!
This car is getting VERY ZIPPY. I can easily see how I could out-drive the suspension if not careful. Because there are SO MANY COMPUTERS on this Prius, it takes a good deal of time for everything to settle down and re-calibrate for better mileage. I guess it's the air mass flow sensor which gets adjusted to the wonderful changes the Gadgetman Groove puts in it's path. That air mass sensor probably gets reset when refueling.
After getting the Groove installed it was about six tankfuls to realize the potential of the groove. And now that I addressed the PCV Valve, it may take another three to four tankfuls for that to fully adapt. All that said, I LOVE THE WORK YOU DO! This groove is great.
I'll take a picture of the PCV Valve so you can show that to other Prius owners. But realize that this is only the newer model Prius, from 2010 on, not the older body style.
Cheers for now,
