There are many choices out there - too many for me to know all the details on each one. I am looking to improve throttle response time, increaase MPG and mostly increase my 0-60 times!

Thoughts and help, please!

Thanks!

 

A chip is not going to improve your gas mileage or your 0-60 times. It will help with the throttle response. It is good for about 12 hp and about 15 ft-lbs of torque. That is about it.

 

Since youre still under warranty I would recommend Revo since its an ECU flash rather than an actual chip that would void the warranty in most cases. Youre not going to see a big gain, the speculated numbers usually are tested with an intake and exhaust because they chip really takes advantage of the two. Biggest gain will be throttle response which is the S4's weak point.

If youre looking for better mpg I think you bought the wrong car.
