Any one have one of these do they like it ? May buy one for my is350 looking for more responsive go power . Does anyone recommend it or any pros or cons thanks

 

Push the gas pedal harder.

Does the exact same thing and it's free.

 

although today's new electronic throttles on pretty much every new car is a lot safer then cable, it does lag a bit. but it's not enough lag to spend $$$$ on a useless throttle controller that will cut your time by fractions of a millasecond when you step on the gas. i'de say, spend your money elsewhere.

 

Your ECT Pwr button does the same thing. When you engage it you should noticed that your throttle response is more active.
