Hi,
My wife has an 06' LT Impala with the 3.9 liter engine. Whenever I drive it, it drives me nuts with the sluggish throttle tip in and response. These engines are throttle by wire so I would assume it is in the ECU programing.
Has anyone installed one of the JET chips and has this made any difference? Is there any other options into making the car a little more lively off the line. I know the car has plenty of power it just takes mashing the pedal all the way to the floor to get it. Any help or info would be greatly appreciated. Thanks.http:http://www.impalaforums.com/images/smilies/confused.gif
