      1) Get a JHM Tune
      2) Drop in k&n filter
      3)It depends on what type of sound you want. Stick with 2.5 pipe.
      Catless and Fast Intestions catback is what i would recommend

      1) ecu tune won't do much unless you have at least piggie pipes and cat back.

      2) intakes don't do anything. If you really want some as trextruk said, k&n drop in will work the best but not much better than a stock one.

      3) as I said cutback should be before tune.


      Order should be:

      1) catback and piggies.
      2) Jhm tune
      3) drop in k&n, if you really want.

      1.8t no
      2.0t no
      2.7tt no
      3.0t no
      4.2 YES!!!!!!!!!!!!!!!!!!

      JHM targets the market apr doesn't want to touch, targets the market nobody can succeed in, not the easy money from software tunes

      1. JHM tune
      2. K&N drop in, otherwise do nothing
      3. your choice but again Fast Intentions 2.5, anything 2.5, headers? piggies? dps? your choice

      i know i mentioned again what was posted above

      Eh....I cannot comment on the other motors other than the 2.7tt and 4.2.. So..

      You do know that Jay was literally the first to get a Ko4 car (2.7 B5) S4 in the 11s right? Especially with a full interrior and spare in the trunk.. He was basically a 2.7tt pioneer, and still known today for his 2.7tt work..

      ^ http://www.youtube.com/watch?v=YeaNy0s2w8A

      But regarding to how JHM specializes in tunes or mods, keep in mind JHM is the "stick to what you know" guys... And Jay owned a B5, loved it, therefore made amazing mods for it and made money doing so.. So now, he owns a 4.2.... And guess what, he's made one of the best files for it, why? Because he has a passion for the car/Motor.. Hell they even took time to make install DIY videos full length for their customers.

      Anyone will create art in any form when passion and dedication is their motivator, not money or fame like other tuning names.

      JHM Standup guys and great customer service, and guys are still humble to this day.

      Seems like no one answered this question of yours. You need to ship it to them. This means removing your ECU, packaging it properly, expedite shipping to them and have them ship it back. Usually takes less than 5 business days. You need to purchase the tune from their webstore first though to make things easier. That way, they can be ready for it when your ECU arrives.

      Well worth it as they're the only ones that have a proper tune for the 4.2

      Also, like everyone mentioned, make sure you upgrade your downpipe (either go catless 2.5" or at the very least, go the "piggie" route (which just guts your cats and leaves everything else as is).

      All the other tunes aren't worth the money IMHO and better to leave untouched if you don't want to ship your ECU to them or alter your downpipes.

      Has anyone here ever tried out different tunes? Either on their own car or from test driving another car that has a different tune but everything else the same?

      I can understand someone saying they love something they've done to their car but sometimes it's fun to compare (and not just regarding tunes).

      I would say the sound is more due to the V8+exhaust than the tune itself.

      Don't bother with the K&N filter,

      Exhaust, downpipes, and tune are the best bang for your buck.

      I've heard great things about the utitronic tue for this car, probably what I'm going to do. They also have different choices such as stage 1, stage 1+ and stage 2, that offer different options.

      As for exhaust, I custom built my own (; and I highly recommend it. Good luck!

      I heard the tune is actually a little dangerous for the motor. I'm not a tuner myself so I can't confirm or deny this assessment. Just relaying what I heard from an actual tuner (who's actual real life job is tuning for a large auto manufacturer). Take it or leave it

      In any case, it's not the best one out there for the 4.2 V8 (BBK) from the B6/7 S4 in terms of power gains (and that's been proven both on dynos and more importantly, quarter mile runs; it's not a subjective statement) but some people like other aspects of tunes (such as multiple settings for warranty purposes and other reasons) so in the end, it's always best to try out different tunes (hopefully at meets and stuff) for you to get a better idea.

      Almost every tune will add some power/responsiveness to an extent. So if you ask anyone that's only ever had one type of tune, they're obviously going to say it's fantastic because they're comparing it to their stock tune. You need to either talk to people who have had different tunes themselves or better yet, try them out for yourself and make your choice then.

      Also, you mentioned you custom built your own exhaust. May I ask the specs? Material used? Diameter? Straight pipe? X-pipe? Do you have pics? Did you only do the catback or did you also custom build a downpipe?

      I still have stock down pipes. That's next, I might do piggies. I have 2.5 inch pipes from the flex pipes into a 2.5 inch inlet/outlet X pipe into two flowmaster super 44's. It's stainless steel. I don't have any pictures though, sorry. but I can take a video.

      2.5" from the flex pipes? The flex section is part of the downpipe though.
      If you're already mostly 2.5", I'd go with a proper 2.5" downpipe set up as well. Just doing piggies will leave you with 2.25" (although I'm sure you know all of this already lol).

      Well, good luck with your ECU research. Let us know what you end up getting.

      Hahah yea I know, I went as far as possible before pretty much running into the curves up. Doing the piggies is just the easiest right now, I haven't decided what I'm actually going to do yet. And thanks! I'll let youz guys know.

      Currently I run the 034 intake, does't do much but it looks nice. Also I have a Uni tune and Ill soon be switching to JHM. You get a lot more for your money, as everyone has said before its proven. Its all over the Zine. Also I run Catless Stratmosphere exhaust with just the x pipe. no resonators. Haven't heard anything better so I recommend that or the FI exhaust. Hope your car turns out nice for ya

      Got some pics of my exhaust set up for you guys.

      This is where I cut into the downpours, right after the flex's and deleted two of the cats.


      This is the rest with the X pipe.


      And this is the muffler set up. (kept the stock tips).

      Setup looks great , but do you get any drone/grogging from this 90 dregree bend? I mean the piping is large enough, but just seems to be a hardcore bend.

      No drone at all, the exhaust is actually pretty raspy. I just cut the cats out of my downpipes and made them into piggies too. Sounds great right now and I can deff feel the difference.

      i picked up a b7 s4 right before xmas and i currently have labree fullback exhaust. downpipes and catback. i absolutely love the sound. its catted and resonated.
      I'm going with a jhm 91 oct tune soon along with a k&n drop in. the K&N is only 50 and easy to install yourself.
      I've heard marvelous things about the JHM tune so i'd do it if i was you. but i heard the tune is only effective if you have at least pigges. so id say exhaust first
