this is a little review on this throttle controller i just recently installed on my 2006 IS250 manual

Cost was $169.00NZ (137.80USD)

Extremely easy install and setup even though the instructions were somewhat translated terribly but the pictures made it easy

Once set on the particular mode you want to use there is no need to reset the mode when the car is turned off and back on

On the highest sensitivity setting made for easy heel toe changes saving my worn syncros

On the normal setting hill starts are a piece of cake!
I stalled this alot due to me not giving enough gas and the slight delay- the delay is pretty much non existent now making driving around town very comfortable

have yet to try the economy modes as I don't see the point,on normal mode gas mileage is exactly the same as far as i can see.

Overall great product and am very happy with the throttle reaction now,certainly will save the clutch in the long run i think

I was in the mind frame of just push the gas pedal more and not be all thumbs but even my wife commented on the difference just a slight change in throttle positioning made the car a lot more relaxing to drive and to cruise around in.
