On my S4, I've installed the MTM stage 1/2 chip, milltek downpipes and cat-back exhaust. I'm happy with the performance but interested in possibly adding the MTM stage 3 software and fuel regulator to get a little more top end power. I have a connection to get the software for $795 (retail) and have heard that is it is a little more powerful. However, I'm not sure if it is completely worthwhile. For those with the "official" MTM stage 3 setup, did you run the car with the stage 2 software and turbo-back exhaust before upgrading to the stage 3 software? If so, what were your impressions? Did you honestly find it worth it? Any feedback would be appreciated considering I might throw down close to a grand for the new software, regulator, and shipping fees.

MTM isn't exactly a beast for speed, it's very driveable. If you want speed go ABT or XR

piggie out your downpipes too while you're at it.

You can't put the AMS and the XR in the same class, that is so wrong..

Interested in the MTM Stage 3 also. Can you email with your source? I am installing Autospeed DP's and AWE Twin exhaust on existing MTM Stage 1 software and want to maximize the additions
