No, this is just a stage one engine remap.

@jdp1962; if you are doing the remap why not the whole shebang - go full stage 2

Because I'm a cautious man by nature. This is quite a big step for me.@jdp1962; if you are doing the remap why not the whole shebang - go full stage 2

Thanks to @Cerbera9 for steering me in the direction of Audi Badges.
I've just ordered replacement Supercharged wing badges to replaces the eBay copies I fitted two years ago and which are now looking a bit tatty.
Let's hope this time I manage to fit them in the right place. Last time, I missed @Bristle Hound's reminder to print the template in landscape format.

Just come off the phone from agreeing the remap with the insurance company. Extra premium is £30.75 for the rest of the current year, which is to mid-October. Now for the remap itself, tomorrow. 
Out of interest, how did you approach the conversation with the ins company ? Were they familier with remapping and just have a simple loading to apply to the policy or was it not as scientific as that ?
Exciting day tomorrow then ! (we're all still big kids at heart when it comes to stuff like that ! )

Glad insurance increase isn't too extortionate. Bet you must be excited for tomorrow

I just emailed my contact there, told him what was happening and when, and gave him the anticipated gains. He replied later in the day (thus taking care of disclosure) and said he'd call me today to let me k now if there was any effect on the premium.
This evening, I replaced my supercharged badges with the ones I ordered from Audi Badges on @Cerbera9's recommendation. It was pretty easy, using dental floss and Mrs Grumpy's nail varnish remover.
The old nearside badge, looking a bit tarnished, plus it was always in the wrong place because I printed the template in portrait mode:
Badge removed from the offside with dental floss in ten seconds:
All residue removed with nail varnish remover and detailing fluid:
New offside badge in place, using template:
All finished:
And the nearside one, in the right place at last.

If you look on most insurance company's websites they have bands for +10% and +20% power gains. Beyond that you probably need to phone them or get a specialist. When I remapped my B7 by 20% I had to swap to Admiral as Direct Line don't do remaps but it was straight forward and not much extra. It's more common than you think. Ford have Mountune and Volvo have Polestar which are both manufacturer supported remaps.
My insurer is Mulsanne, the in-house insurer for Complete Cover Group, who are represented here by forum sponsor @Tim@Prestige. They're brilliant.
So the car is back from being re-mapped and having the billet transmission mount fitted. I've got a paper printout of the figures, but the garage is going to email me a jpeg version that I shall hopefully post up later on. For those of you who have been waiting on tenterhooks for the results, I fear you may be underwhelmed, as they're not that great.
First of all, the best standard figures they could get on the rolling road before beginning the mapping process was 306BHP (instead of 328) and 318LB/FT instead of 325. From that rather disappointing base, there was never going to be any chance of getting anywhere near the targets of 395BHP and 383LB/FT. After mapping, the best dyno run was 353BHP and 345LB/FT.
In fairness, the air temperature was about 28C. They reckon they can get better figures on a cooler day. They also realised rather late in the day that the air filter housing was clogged up with leaves. I'd told them the car has just had an inspection service, and I think they'd assumed that had included a new air filter. They removed all the rubbish from the filter housing but there wasn't time for another dyno run, plus the temperature was still well up. So we left it there for the day.
Ultimately, it's how it feels when I drive it that matters, and I've not taken it out for a run yet. The plan is to give it few hundred miles of hard-ish driving, put in a new air filter, and then get it back on the dyno on a cooler day; see what figures it then pulls.
I'll add the dyno figures when the attachment arrives.

Ok, so I've taken a photo of the print-out, and here it is. One thing it does show is that the rev-limit has been raised from 6,000rpm to 6,500rpm.
Here's a more readable view of the results. I've just emailed this to my insurance guy, saying as it's less than expected, can I have my extra premium back.

@jdp1962, thanks for the share. Tbh I am not disappointed at these numbers and this yet again confirms that Dyno Dynamics reads ~12% lower in peak powers than Mustang or Dynojet. Whilst I agree that there are many other factors I believe the biggest factor here is the dyno being used. I am sure if you use any other tuners your numbers would be close to what you were expecting.

I agree with @Tashfeen - those are dyno calculated figures so don't necessarily pay too much attention to them. Does the tuner do a lot of S4s? If not it may not be set up quite right to truly represent flywheel figures. Looking at the gain, you have 15% more power. If it was indeed at 28C ambient and the car was hot (the chart shows run 22 - how close were those runs done together?) then 15% is OK. I have three questions:
1) Did you have an s-tronic remap done? I didn't think you had planned to.
2) What fuel was in the tank? If it was Momentum or V-Power, what had been in the tank before (i.e. is there a chance you have octane dilution?)
3) Any air intake mods?

- No remap of the S-Tronic box;
- I switched to V-Power about a 1000 miles ago; first fill was about 55 litres, by now I reckon it's probably up to about 90-95% V-Power;
- No intake mods (other than clearing out the leaves ).
The tuner isn't an Audi specialist but has worked S4s before; he's also just recently worked on an RS6 (4-litre V8 turbo).
No 2, is a fair point that I completely missed @Dippy. If we look at Sanspeed website their Stage 1 tune for an RS4 gives only +22bhp. It would be interesting to see exactly what they do as part of their stage 1 remap. It looks it is a simple chip-tune giving a maximum of 15% increase on an S4.

Good feedback guys; in the end it's not the bragging rights of the numbers that matter. I'll report properly on how it's driving after the weekend.

1) I thought so. Your graph shows rev limiting at about 6300rpm for the remap and that's correct for the stock B8.5 gearbox map. I don't know why the revs drop sooner for the pre-remap runs, but stock power usually peaks at around 5500rpm anyway so that doesn't matter.
3) My guess is that's what is flattening the power curve at the top end. Most cars with TCU remap and air intake mods will show the power keep increasing to the redline, and most definitely at 6000rpm. But yours flattens from just above 5500rpm. I could imagine your peak rising to around 370 with uprated filter and pipe, and likely more with cooler air. Then a TCU remap would put you near 400.
Anyway, you must have noticed that extra power even though its a bit less than you expected?

Ok, so we drove to Sevenoaks and back this morning; not a comprehensive test, but enough motorway entry slip roads to accelerate up (or down) using S mode and the new redline. Has it transformed the car into a beast? No, of course it hasn't. What it's done is taken an already effortlessly fast car and given it marginal gains at every point. If that sounds like damning with faint praise then so be it. It's what I was looking for, and therefore, was worth the money.

If you are happy with the performance @jdp1962, then that's all that matters

Not even getting in the car today. There's no point; it's 33C out there and the roads in Kent and SE London are chocka with Father's Day traffic and people flocking to Bluewater for the air conditioning.
Apologies in advance if the following is an uneducated numpty question........ What is the reason for the fluctation in the torque trace (and also evident in the bhp curve but less so ) between 1500 - 3300 rpm ? My uneducated mind would have thought it would be more linear ?
Glad that your pleased and has satisfied your expectations of the map, for me, its really about the improvement in day to day drivability, I think your comment " What it's done is taken an already effortlessly fast car and given it marginal gains at every point " really sums it up.

I'm not sure but I like to think it was the ESP fighting to stop the car from breaking free of its shackles and tearing off on a rampage all on its own.
I hate you.Yes, this is the time of year when the effort and expense of putting aircon in my home office is justified...
@jdp1962, Jeff I now feel exactly how you felt when you went for the map. Had exactly the same issues where the car was down on power significantly (30-40ps). And it is due to weather. Us B8.5 lot have to keep our cars cooler in summer if we are to get the desired power gains. So, you are not alone in this
