Stock: 347psStage 1:436
And there was someone on here calling custard for 75hp gains!
Good to see Chris has got his own B8 S4 and is going down the tuning route, I shall be interested in what he makes of the car with the extra go. I am not surprised at the need to upgrade the brakes either, it is in the back of my mind that the relativley low cost tuning will be shadowed by the cost of the inevitible RS 8 pots to go on the front.
I am teetering on the edge of a remap myself and when I do it will be from MRC no doubt. That said it will be interesting to hear about the REVO tune. The 410hp after figure sounds low, but then it looks like REVO are now quoting the stock figure as 333PS (as Audi do). Most people achnowledge the engines put out more like 350-360PS when healthy. I've even seen REVO material state the cars dyno higher than stock, although in the same context still only quote 416PS for their stage 1 map.
While I won't suggest a need for modified intakes etc at stage 1 tune, I do suggest you check the airbox. Audi service schedules will only see a service technician open the air box every 57K miles or 6 years! After only 34K miles and 30 months mine looked like this:

57k or 6 years??!!!!! Is the same interval applied to V8 RS4s - could be why they have cylinder head woes?NGK210 said:

Not sure if the same on the RS. It is quite an interval though isn't it. Plugs also have a very long service schedule but they looked fine in mine (any doubt and they would have been changed). The s-tronic (DSG) oil has it's first changed before the air filter! It will be interesting to know if the filter is changed and when on Chris' car. An 09 car, 58K miles and full Audi history. Did the dealer have the foresight to fit a new filter at the service before 57K miles rolled over or not?My car is on fixed inspection services as I do not match the variable long life criteria of "driving style: Moderate acceleration, moderate braking,
engine revs mainly below 3,000". Who buys an S4 and meets that? Someone trying to get the combined 29mpg I expect. The fixed inspection just means it gets a fixed annual or 9K mile oil service. The Inspection services are still 2years/19000 miles - hence brakes and schedules that look at filters and other additional work are not very frequent. If owners and dealers are not on the ball, you could have a inspection service at 4 years and 45K miles and not have the filter replaced and your dealer may not change the filter until they see the car at 64K miles.
When we inspected mine, I had a new Audi paper filter popped in anyway. It will have about the same time/miles until Audi do it on schedule and then I will do an interim one again next time too. We also dynoed the car before and after and to be fair it made the same power, so the dirty filter after 34K miles was not a problem, but at nearer 50K would that still be the case? Some leafs fell off when the lid of the box lifted, but you can see how they are sucked against the filter and again approaching 50K miles how much worse would that be? If Audi want to have long schedules between filters for low cost fleet service stats fine, but on a performance car I think the airbox should at least have an interim inspection and clean out.

Not really too worried or interested in dyno figures, care more about performance data and drivability. Overall aim is a v.discreet small wagon capable of staying with very fast cars we shoot that will average 20ish mpg and do 0-100mph in around 10sec regardless of weather.
Picking it up this afternoon!

I'm looking forward to hearing your thoughts on it over time/mileage.Picking it up this afternoon!
All the best.

But why an S4 over a 3/5 Touring? I'd have thought the latter to have been more up your alley.Rawwr said:

That sounds fair and probably very wise. I think you will achieve your mpg unless it is driven hard ALL the time. OK maybe you won't!Picking it up this afternoon!
My standard car has recorded 0-100mph times of between 11.0 and 11.5 using a Racelogic Performance Box. So your 10 sec 0-100 also looking very likely.
Enjoy.

But without dyno figures you can't see the before and after. Get it to MRC and have a RR done before and after and then come back and tell us if you manager the 0-100 in 10 seconds. If you go for the stage2 I think you will accomplish your target.Picking it up this afternoon!
