S6 V10 JHM tune

Get r done, and lay down some nice runs before it gets to warm :slight_smile:

Amazing to see JHM taking a medicore performer widely under appreciated platform to the next level!

It’s been a while, car has been running great, although I haven’t been able to make it to the track yet.

I had been waiting for the JHM exhaust, but since I couldn’t get it in time, I thought some maintenance issues should take precedence. Maintenance will include replacing filter housing o-rings and new idler/tensioner/belt. Although i had carbon clean 10k ago, will be taking a look while manifold is off to check for buildup/look at injectors. I’m very curious to see what it looks like.

I am also having lw balancer, lw rotors, SAI delete, new tires- going with the AS3+'s, my second set, I think they ride and handle well overall.

I’ll update with my thoughts on the lw rotors and balancer after I get some miles with them.

Nice update, look fwd to your track times with the lw parts and maintenance.

And cracking the intake every 10k that’s one way to keep it running tip-top :-p

So are there any dyno results before and after the tune?

You’re not going to see any dyno results from JHM themselves as they prefer to measure performance by 1/4 mile timing rather than dyno testing since dyno results don’t always show the true performance of a product/upgrade.

Very true. It was because of all the dyno claims from other companies in the past and actual zero improvement in 0-60 and 1/4 mile times that for years nobody bought tunes or wasted the money. until JHM came out with there tune and proved there tune made your S6 not only funner but almost a second faster depending on the mods. unheard of none of the other big box tunes have results even close to this. Even the biggest name tune next to jhm has been tested and the results were no faster or almost no faster acceleration than stock, but there dyno sheets from these companys looks great… so it turned into a prove your product did more than just get a printed out dyno sheet.

This is my first post. I bought my V10S6 brand new in 2007. I love the car and its only unscheduled maintenance visit was when a wayward rock punctured the radiator. It was misfiring about 6 years ago and on the next scheduled visit, the valves were really dirty and were cleaned out. Since then, it has only drank top tier 93 octane and I am diligent about giving it an Italian Tuneup as often as I dare, and it has not misfired since. It was stock except for 19’ Oz Leggera HLTs in the summer. Currently it has 18 inch wheels for winter duty. It turned 10 years old last month and it was time for a makeover. I perused the excellent information in these pages to determine what mods to make and the car received its second ever carbon clean (not as dirty as before), 115K service, intake spacers and gaskets, K&N filters, and the JHM ECU tune. I picked it up yesterday and my smile on first drive was as big as the one I had when I picked it up from the dealer 10 years ago. Its a different animal now. The JHM exhaust is on backorder. Will probably do the lightweight rotors when the current ones wear out and add on the other lightweight parts. Thanks to all of you guys, I couldn’t and wouldn’t have done it without your input.

Original s6 owner, you are a rare breed!!! Have fun with the new mods you have chosen well!

Mark my words, you will re-fall in love with your car after the exhaust goes on! Have you made it this whole time with the stock exhaust or are you running a Milltek or custom fab? Also, if you’re still on the stock wheels, aftermarket wheels are considerably lighter - mine are about 13lbs/corner. With the LW rotors, that’s close to 30lbs per corner! it’s probably the biggest change in feel upgrade - almost more profound than the tune since it affects accel, deccel and turning in a dramatic way once all that weight is gone.

What’s the cost of a JHM exhaust?
Might do the exhaust and tune this year…

vtgt: Thanks!

I’ve been going with the stock exhaust the whole time. I am eagerly awaiting the JHM pipes with should get here in a few weeks. I was tempted to pull the trigger on the Miltek exhaust numerous times and I’m glad I held off. I’m a man of science and didn’t really see any improvements in 1/4 mile times in my internet research until all these JHM parts came along so I’m glad I waited. My summer rims are Oz 19’ inch Leggera’s so I think I’m saving a few per corner. My rotors are stock and still relatively new so I’ll wait till they are worn and will swap them out for JHM lightweight parts then. The JHM ECU tune (and carbon clean) really makes the car a lot more fun. I have a 911 for the track and the S6 really is not a track car, its more of a grand tourer but now I’m tempted to stretch its legs for real once more this summer, that should wear out my current rotors so I can get the lightweight JHM parts! :slight_smile:

Yeah the milltek was the only thing available at the time when I purchased my car… made it sound amazing but no additional performance at all. I’m still happy with it, but sucks because if I want to upgrade to the JHM Pipes I basically will be stuck with a $1200 paperweight. ugh… and who do I sell it to? lol.

It issss a track car… Just turn off the traction and stability management, add bilstein dampers, and a good set of tires, and you’ll be amazed how well it holds up against just about any other GT car… If we had a S/C kit available and I hit the lottery, I’d dare to say it’d be faster than most sports cars.

Your talking to a guy with a Porsche. You’re not going to convince him. And, respectfully, there can be no comparison between the S6 and a 911 at the track. The handling of the 911 is superb. This is no disrespect to your car and all the amazing mods you have made. I look forward to doing many myself after hearing from you.

If you take it to the track, its a track car I guess. I’ve taken the S6 to Road America a couple of times and run with the Novices. Audi club Driver Education events run 4 groups: Novices, Intermediate, Advanced and Instructors. I drove Road America for hundreds of laps on my Xbox 1 (Forza) to memorize the track. RA has 3 long straights when you just floor the throttle, and then you have to break hard in order not to fly off the track on the following corners. It is better than sex as its 30 minutes of pure adrenaline 4 times a day for 2 days! During the downtime between sessions, one can just wander the paddock and talk to other car nuts. During one of the events, there were 2 professional SSCA race car drivers hanging out in track suits and their gig was this: If you sign a waiver, they will drive your car with you in the passenger side so you know what your car can do in professional hands. How could I pass that up? So this dude, Mark White, gets in my car and I strap in, and he proceeds to drive my S6 and ran with the instructors. The instructors are all car nuts and most of them have dedicated track cars that are not street legal. Corvettes, 911s and such. He ran one lap to get the hang of the car and proceeded to take down everybody in front of us by barely braking for the corners. The S6 on street tires was blowing by Mustangs, Corvettes, and Porsches driven by instructors on slicks. This guy was a pro of course and he drove the car to its limits but damn, I knew then as I know now that I will never be able to drive like that. That was the biggest rush I have had in my life! After the weekend, I had to get new tires, new rotors and new brakes. $$$ but was it worth it? You betcha! Now that I have the 911, its what I take to the track. Its lighter and it costs much less to track as its much easier on tires/pads/rotors! But maybe its time for the S6 with its new mods to get back in there!

Wow. that sounds so amazing. We don’t have a track close to where I live that is decent. I wish you had go-pro or similar footage of this, would be awesome to see the car on a track. Has me wondering what my air bag suspension would fare as well as an excuse to upgrade the brakes. Oh well, I will dream through your experiences lol.

This all sounds about right. If you drive it, they’ll get out of the way lol… The braking ability of the car is what makes the difference I guess. That plus Quattro and the sport diff (with everything turned off). With the pedal sensitivity that comes from the tune, that also adds another element. Add dampers and you’re ready to go. I can cosign the part about the need for new pads/rotors etc after a track weekend. I’ve had my rotors replaced I think 2 or 3 times over the last 14 months or so. Pads, maybe 3-4 times. Tire technology has come a long way, so I haven’t had much of a need to replace tires. Maybe more often than if I hadn’t gone to the track days, but they don’t seem to fade away quickly.

Unfortunately, I didn’t have a go pro then. Sorry to hear about the dearth of tracks near your home but when something is so much fun to do, then near becomes a relative term. i.e. 10 miles is a long drive to get a root canal but 200 miles is not too long to get to a track!

Having driven this car for 10 years now, I can say that the JHM ECU tune really wakes it up. The accelerator pedal is so much more sensitive which is mostly good - the downside is you have to be more careful getting it off the line as it can get away with you very quickly from a standing start, specially in sports mode. I drink my morning coffee at home now, I don’t take it with me on the morning commute. A part of me wants to start driving with the transmission in D, but the other part says after 10 years in S, why start now? My compromise is to get off the line in D, then shift to S when rolling. I agree with you on the advancement in tire technology. The Michelin Super Sports I now run seem to wear much better than the OEM Continentals that came with it from the factory. Cheers!
