I apologize in advance for these questions as they are redoubtably repeats. That said I have spent a great deal of time reviewing past posts on these topics but want to make sure I've got everything straight.

08 S4

Proposed Mods:
1.) ECU - (Stasis?)
2.) Exhaust (Militek, Stasis)
3.) Intake (Read mixed reviews)

My questions is, before spending a few thousand dollars on these mods am I going to feel noticeable gains? If so, how significant? Worth the investment when considering I don't plan on anymore mods for this car (waiting for the new RS6)?

Thanks to all.

 

If you're waiting for the new RS6... its not coming to the states. If you get all of these mods done you will feel a difference. Dont forget downpipes also. To get the full benefit of the chip you need the exhaust and intake to help the engine breath. If I had the money I would definitely do all of these. If youre looking for a huge gain, get the AWE supercharger when it comes out. With that you'll be quicker than an RS4.
