Tuning The S4

[as400]

What are the main ways to go to get more out of this car?...as its non turbo is it worth re-mapping?....is supercharging the way to go?

To get any decent power out of the engine, you'll need to supercharge.
Staying N/A will cost more than it's worth

Do you really need more that much more!??
If your answer is yes and your after big numbers save your cash trying to tune the s4 past exhaust and filters - i would buy rs will be cheaper in the long run to be honest !
