its alright does what its supposed to do and tricks the computer into being under load to run at v8 mode all the time. doesn't solve rough idle issue doesn't increase hp or mpg it only removes the v4 mode. thats it. not worth the money but you got 3 options ,this, the other brand, or buy the tuner. wish i would of bought the tuner now instead of later. if your tight on money but really want your v8 to be a v8 then this works .. but needs to be ALOT cheaper.
