Right, I know this question has been asked before about R32's but from what I can find, info is pretty rare on a the a3's.
Basically, has anyone had their A3 remapped? What are the gains like and would you recommend or not. Would also appreciate R32 experience. (Preferably from an owner so we don't get into a N/A remap debate!)
Currently have a forge intake fitted which I guess will be a bonus to the map. At the moment I'm looking at Revo (£300) and Superchips (£230), any other companies worth considering?
Anyone have some wisdom to share with me? Or rolling road figures?

The results would be the same as with the R32 as they use the same engine!
Having had it done and spent money on other mods (high flow cats, 'performance' catback system, intake changes), I'd not bother. I've gained around 15bhp and similar torque with the changes I've made and a good glug of that is down to the increased rev limit. It feels more alive as a car and the engine feels smoother in action but, performance gains in terms of speed and minor.
If you ignore that, as I did when I asked a similar question, avoid Revo like the plague. I initially had their 'stage 2' map on mine and it was worse than stock. It leaned out as the engine loaded up instead of richening. That resulte din a flat feeling response and considerably worse fuel economy. Horrific! The only place to go is Stealth Racing in Banbury. They custom tune the ecu on a dyno and my specific example made 11bhp over the Revo map that was written over.

My butt dyno registered a change after I fitted the high flow cats. Urgency/ low down torque seemed to increase to a noticeable degree. By contrast, my butt didn't discern any difference when the catback exhaust was fitted or intake changes were made.
I suspect the remap increased power/ torque the most though but, as there was an improvement across the entire rev range with the largest increase (in bhp) being in the high rpm range, it's more difficult for the butt dyno to quantify it.
One thing to note, if you fitted high flow cats, you'd need to get the ecu remapped anyway as it will throw a CEL, due to the rear lambda sensors complaining.
It's also worth pointing out that on your car with the 2 extra silencers in the front pipes, the sound will improve with an aftermarket exhaust system much more than it would with the R32. That is a good reason to spend money on an performance exhaust system.

Mirroring the not good VFM thoughts. I've dabbled with R32s a fair bit over the years. The most I gained was about 20hp in an otherwise standard car. The best I've seen an R32 engine make, albeit in a MK2 Golf as a conversion, was 296hp. That had Schrick cams in it and Stealth Racing mapped it.
The engine is restricted by it's intake manifold. It's capable of more than 300hp, but you have to dump the intake for an aftermarket one and in doing so, you lose 50lbft from the midrange instantly.
Don't mess with the cats and especially not the downpipes imo. Again, dropping them kills the responsiveness low down. It's one of those cars where you have to love it for what it is, or sell it and move on I'm afraid.

The extra silencer has already gone http://www.pistonheads.com/gassing/topic.asp?h=0&a...Paul
Anyway, that's 2/2 saying stelth for your maps? I guess that's 2 votes for them...
I expect I wont really get much value from a map, but the not knowing whats possible from it may force me to do it! Just to even understand the changes
Do you know any companies that will let me 'try before I buy'?
I realize that is a piss take to ask if its a custom map though

Unlikely. A remap of the Revo or Superchips caliber takes 2 minutes to upload to your ecu?! The guys at Stealth would spend 20 minutes just strapping your car down to the dyno. That's after they've spent the time getting your car in the air to disconnect the Haldex controller (they use a 2WD dyno). Then they'll spend an hour or so actually mapping it.I realize that is a piss take to ask if its a custom map though
It wouldn't be worth their time.

After a year of faffing around I decided to get a remap, I know the recommendation was for custom, but I came across an offer too good to resist on Revo stage 1, this is coupled with a forge air intake.
Main advantages are..
If anyone is in the same position I would recommend to go with it, the change is subtle but defiantly noticeable.
I can update you about the MPG once I decide to drive with my eco hat on
Main advantages are..
- Mid range torque is improved, the pick up at any RPM the most noticeable improvement. There is no longer any flat spot and it is unbelievable how linear the power is.
- There used to be a few nasty shocks parasitically when coming off the throttle, these have now all gone and the engine is much smoother.
- The power increase will mostly come from the raised rev limiter as suggested, Revo raises it from ~6800 to ~7500, the engine is happy to pull to that RPM, but I haven't done it too much, can anyone recommend if it is safe to do >6800?
- Surprisingly one final improvement which I wasn't expecting is the engine sound has improved! The spark timing was adjustable which is the only this I could think to cause this. Even the girlfriend who has no interest in cars said it sounds 'more like an F1 car now' without me mentioning anything

This, sound advice from someone who knows what they're talking about, you either love the sound and feel of the engine, or its time to move on

It's the not knowing how the remap would feel that made my jfdi!
But, ignoring all the above I would love the supercharger 😎

The R32 / 3.2 valvetrain is known to be unstable at those kind of engine speeds. I wouldn't exceed 7000rpm personally.6600rpm is the standard rev limit if I remember correctly.
