Hi,

I'm considering a performance upgrade on my Audi A4 2.0T Quattro Tiptronic. If anyone has had a 45-50Bhp increase please share with me your experiences.....

-Performance change
-MPG
-Reliability
-Anything else!

Many thanks.

Not owned but driven loads; performance change is marked. There is no sudden kick in the pants, torque curve mimics the standard one but there's just so much more of it, build of power similar but again with more of it and a slightly better power band.

Fuel economy will be slightly improved under normal driving, some people report 2-3 mpg, others as much as 10. Totally down to your right foot, this is a bonus rather than the reason you'd remap a car (you'll need super unleaded if you're not running it already).

Fit an uprated diverter valve at the same time as the map for peace of mind; remember that you're asking the same hardware to do more work so be nice to it! Our very own lovely Mr TT thoroughly reccomends carefully warming up and cooling down the car before and after driving hard.

Thanks Dr G.

The main reason for an upgrade is that it's a heavy car to shift with circa 200Bhp.

I've still got 8 months of my Audi used car warranty, so that's really my only concern.

Do you know how easy the divertor valve is to change, and are they costly?

Many thanks.

sorry to go slightly off topic, but are fuel consumption gains as apparant on N/A engines? considering a remap on my A3 3.2 mainly for the improved fuel consumption, and also for a bit more fun on a sunday afternoon.

I don't think performance upgrades make a much difference to mpg in n/a engines, they're mainly done for improved torque, and access to it.

If you look on the Audi website i think they offer remaps that won't invalidate your warrenty.

I've looked on the Audi website, but nothing doing on there. I know BMW offer their own performance upgrades, all Audi seem to do in cosmetic stuff......hmmm!

I'm thinking of using Auto Performance in Brackley.

Can anyone recommend any other tuners? I'm aware of Revo and MRC.

Many thanks.

Ive heard of Custom Code and GIAC too I believe. All very similar though. I would go Revo.

Hi,

Cant comment on the Petrol remaps, but I had a Koch (yes very unfortunate name) remap done on my 2004 A3 2.0tdi Sport. It was rolling road tested at about 150bhp (instead of audi's quoted 140) before the map, then afterwards was reading 192 but was told it could be more but my clutch was slipping a little :-)

I have done almost 20k in the car over 2 years, and the only thing I would say against it is that it seems when I change fuel type, i.e. BP ultimate to tesco standard the engine seems to smoke for about 100 miles before the engine re-adjusts itself. If I stick with one fuel type it seems to stay stable.

On the plus side, the car is a totally different beast, more torque, better throttle responce, less turbo lag and no change in fuel consumption.... if you drive like you are driving miss daisy then it could be slightly better but I dont ;-)

Best £400 upgrade I have ever done on a car....

Do ittttttt.....

Hi there i can say from personal experience that Revo is the way to go. They flash there software onto your ECU and you can buy a switching module from them to turn performace mode on or off. You get a good power increase of about 65 bhp and the torque goes up by 100 pounds feet or so. Trust me you notice the difference and the car behaves just as normal when you are driving it slowly. The best bit about the whole thing is the fuel economy is much improved after the upgrade when driving normally. I had Revo software on my car for 27000 miles with no problems and the dealer did not even notice when servicing. Hope this helps.

Regards Phill

Do you have a dyno report to back this up?scratchchin


Proper Dyno, not "bum" dyno.

Personally, I'm only looking at 40Bhp, I don't want to go OTT and put any undue strain on anything.

A company called Shark Performance seem to be getting good reviews for remaps on the Octavia with the same engine.
They have a device where you can download the existing map from your car, email it to them and they send you back a remap to upload to the car.
No connection with the company and never used them, just another option to consider.

Cheers. That sounds like Bluefin.

I'll have a look.
