I own a 2010 S4. I am considering performance upgrades. Can someone help me with priorities. I am considering exhaust, intake and chip. I use the vehicle for 'every day driving'. It's probably the midrange 'grunt' I'm searching to improve (as if the S4 needs any improvement...). Thanks!

 

Im new to audi, but I do have a performance vehicle, but Ill try to help out with my opinion.

Its my understanding that the new s4 is supercharged, as was my car from the factory. All superchargers run of some sort of cerpentene pulley, centfrifugal and roots types. if you put a smaller pulley= more boost = monster hp gains! I would do this if It was my car, the one thing I do not reccomend is getting some can tune from a chip or flash tuner that is just a base line of where the air and fuel mixture need to be.

All cars are different! If you want the safest and most reliable results I highly reccomend you take it to a reliable performance dyno shop have your ride put on a dyno and tuned that way.

No 2 cars are alike, your s4 will make different numbers than the rest, and will requre different tuning! As for what supporting mods you need for this pulley upgrade, I dont know, I have no clue yet what these cars can handle in stock trim.

Just keep in mind you want an exhaust and cold air intake wich will run you probably in the range of $1500+ and you will gain maybe 35hp to the wheels, you pulley that car and dyno it it may only run you $500-600 and I guarantee you will see 75-85hp on this alone! Hope I helped.
