I'm south coast based and have heard some good things regards Southampton's DMS but heard a lot of good things about MRC as well though obviously a lot further to travel.

Anyone here had a DMS remap?...both companies seem to be offering a stage one for £1100 giving about 440bhp.

I haven't looked into APR/Revo or others as it starts to get too complicated!

Am interested if I should be considering air intake/intercooler upgrade or if standard is sufficient on a Stage 1?

I haven't used either, so can't say which, but know MRC are good. Not heard anything of DMS.

I know prices have increased for everything, but for a stage 1, that seems way over priced. I paid about half that and that was for a stage 2 tune ECU and TCU.

I modded my air intake, cost me about £120 and a CTS pulley was £350. I fitted both myself, then went for a stage 2 remap. Didn't go for stage 1.

But just noticed you are B9 :D But I see no reason why a B9 stage 1 remap should be much more than £600. No hardware is changed, just a new map?

Most only upgrade the intercooling when stage 2 plus. Not sure on the B9 limits, but stage 1 and stock everything will be fine.

I can vouch for MRC - good service and they provide dyno results which seem consistent across owners. I know nothing of DMS but their website shows 400 bhp & 520 Nm for an ECU remap which appears typical for a without TCU remap. I agree that £1100 should get more than that so if they are quoting 440 bhp then I wonder why. A TCU remap to raise the redline tends to only add about 10 bhp because power is flattening off considerably at the top end.

A before and after dyno graph is great for a tune. Not only does it show that the stock tune is giving in the order of what Audi told you is should, but you can then clearly see the difference that the tune makes.

Not sure if a TCU tune is needed on the B9 as it is turbocharged and turbos will give all it's puff low in the rev range. A supercharger's speed or 'puff' is more relative to engine speed as that is how the supercharger is driven. Adding an extra 1000rpm on the top end of a supercharged engine also spins the SC an extra 2500rpm (pulley ratio dependant) so in this case you get more power, but in order to do this the gearbox needs a remap to raise the rev limit otherwise it will change up a gear.

So I think for stage 1 on a B9, you shouldn't need a TCU remap too?

Regarding the TCU (gearbox) tune, I don't know the factory torque limits, so this is a possibility of why the TCU tune needs to be done?

Most other places offer a stage 1 remap at around £600, but they may not give you the expertise in Audis that MRC give you and the outright power. MRC do tend to give the best power outputs! :) Plus you get to sit back and relax whilst MRC do the tuning, but again this is what you are paying for.

How good are you with laptops? Have you considered mapping yourself with Integrated Engineering? They're big in the states and you can choose your own personal options, like crackle maps, raise neutral rev limits etc Or choose which fuel you are using. :) I would consider this option now, but didn't look into it back when I got mine mapped. The map is £580, but you do have to buy the IE upload link kit which adds an extra £150.

Response from DMS in Southampton today...

These are responding awesomely to tuning, we are seeing 445bhp and another 100NM of torque on a fully stock car. We will include the compatible remap for the ZF box at the same time. The retail price is £900+vat, but I can offer this at £700+vat. This includes moderate pops and crackles.

This price includes fine-tuning on one of our 4WD dynos and our full aftersales software support package, this is three years of unlimited callouts to either reinstall the software if it is overwritten during a software update from the main dealer. These callouts are unlimited, free of charge, and we will come to any location required.

I did have a look at their website yesterday and it does look good and a quality place!

There are plenty of option out there, so have a look at them, research and choose which is best for you, price, location, amount of extra performance (although this can vary and most tuners will give a lower power figure so when you get more, it's more pleasing :) )

Yes am tempted by DMS, good price, reasonably local and they have done a ton of very high end cars...lots of favourable reviews and good comments on Pistonheads gassing etc...

I missed that this was for a B9 S5. I understand that the ZF OE tune for Audi is not great so an aftermarket tune will be snappier. Based on the limited information available it appears that there is a difference between MRC and DMS in their strategy. MRC has gone for a higher peak torque whereas DMS are keeping the torque higher at the top end in order to achieve a higher peak power. It looks like the cats are restrictive on this platform. If I owned a B9 I'd be inclined to research it a bit more and might even have a chat with Doug. Turbo tuning does require taking heed of the compressor map and exhaust back-pressure, so their strategy for stage 1 might have technical merit. Also from my memory of my B5 S4 it was that "shove in the back" feeling of peak boost that brought the smiles and the MRC tune seems to do that best.

I'm also looking for a Tune same thoughts as you. MRC are well known for their high achievements as they have took time to release this tune for the S5 B9. However I do like what DMS have to offer also and its a hard one! I think MRC advising of revised coil packs maybe because of the extra torque etc?? so the price will increase
