JHM C5 A6/S6 4.2 Development

[Dan@JHM]

As some of you may know of our involvement with the b6/b7 s4 and the products we have developed and will continue to develop even more, you may not have known we got our 4.2 start from the c5 platform.




Its time to show you some of the products we are working and services we offer for the C5 as well.


This is just the start:


First off yes we do have an ECU(engine) and TCU(transmission) tune for the C5 4.2. The engine tuning will be very similar to our b6/b7 s4 tunes, we optimize the tune to give you as much performance as possible while leaving all the safety features in to be as safe as possible.



Pricing:

Ecu = $500 plus shipping

Tcu = $500 plus shipping

Combo = $900 plus shipping

*Note* you must send your ecu and tcu in to be programmed, turn around time is same day if not next day at the latest.


The downpipes we currently are running on our 4.2 are "piggie pipes". They are basically modified stock downpipes where we remove the pre-cat and relocate the secondary o2 sensor so you will not get a catalyst efficiency code. We currently do not have a set of C5 4.2 downpipes in-stock at the moment but can modify any ones that sends them in. If we get enough interest we can make full 2.5" downpipes for this platform but is up to you guys really.




The cat-back we are running is a custom setup using a high flowing x-pipe design. As with the downpipes, if we get enough interest from you guys we will work with FI to make a full cat back system just like the b6/b7 s4:
