Well I finally got a chance to try out the DNA stage 3 map at the SCN RR day. The car made just over 280bhp but I choose the smoothest graph. Apparently I could get more power with more boost so I will be in touch with John at some point for a tweak.

Anyway not bad for a car with 102,000 miles on the clock.

Wheel BHP

good results there power curve is very good at the top of the rev range bu not a good dip at 2500rpm. i wouldnt tweak for any more boost. the torque is already peaky before it settles, any more and it would increase the spike. Id get him to smooth it and then it'd be a very good power/torque curve and result

Paul was meaning more boost at higher RPM to get more BHP. At 6000k where peak BHP was produced I am only giving 0.86bar boost with a duty cycle of 65.9 so plenty of room for extra boost at top end and with the S3 cooler it should be possible.

Oh and Paul @ RS tuning thought I had a DV leak as the BSH intake was goosing like mad at high rpm but I think that's just the way thoughs intakes are?

Do they give you a print out with measured wheel torque or do you only get the estimated flywheel figures?

I've added the AFR and wheel BHP for you mate.

How much did all the mods cost to get to this stage if you don't mind me asking, just a rough ballpark figure. Because I can imagine that makes for a very rapid road car - the power and torque are produced for such a large amount of the rev range I bet it feels faster than the 280bhp suggests.

Personally I think I'd go this route rather than K04, because you need to start huge chassis mods then to cope with 340bhp through the front wheels, but a stage 3 with those figures would suit me perfectly.

Yeah you'll need a LSD for k04 I would imagine.

Here's what I did, firstly DNA stage 1-£150 ( now £199). The clutch started to slip so I got a Sach clutch and new flywheel at £900 iirc. Next I fitted the following:

2nd hand 3" decat down pipe £75 + £60 fitting

2nd hand APR HPFP £300

BSH Trueseal £150

2nd hand S3 intercooler £100

DNA stage 3 upgrade fee £150

Yes the car does have a good kick!

That's a bloody cheap way of scaring lots of big power cars!, I would imagine the mid range figures are pretty impressive, you ever timed it?.

No I've never bothered to time it. TBH I only use it on the road, not really bothered with 1/4 mile times etc.

The HPFP is a big help with mid range as it allows you to run higher boost pressure longer.

I meant timed as in against a watch, say from 30-100mph I know its not that accurate but gives some indication. I know qtr mile is irrelavent as most of that is down to launch technique. I've seen 300bhp cars run 15 sec qtr mile times then 13 secs the run after, purely down to tyre pressure, launch technique etc.

Not heard of clutch slip purely from a stage 1 before, anyone else experienced this? Especially on a tfsi where you're looking at 235 bhp tops.

My car had roughly 95k on it when I got it mapped, the clamping pressure in the standard clutch just wasn't up to it at that mileage. There was plenty of life left in the clutch just not enough clamping pressure.

No I've not bothered yet and have no figures to compare too.

You can't knock that wheel power for the money spent

Just goes to show, you could spend double the money and come away with less fun than this, and it's not as if you're trading anything other than "badge prestige". I would upgrade to an S3 over these cars but nothing short of that would convince me it was better money spent than an Octy with mods.

Looks like the HPFP is more than up to the job given the AFR chart, seems like the tuner is playing well on the safe side. If you can get more air in there it looks like there's a fair bit of room to unlock more power at the top end.

Spoke to John yesterday, he's not keen on altering the map as he's concerned too much top end boost would cause high EGT's and make the ECU pull power back.

I agree it does look like there is room for more top end boost but I don't want turbo blowing Revo pressures. I saw a few Revo graphs and TBH I didn't like the way many of them ran so lean. Like I said my car has now done 102k and with this map I believe it will keep good power whilst retaining reliability.

I would like a cat back Miltek next and possibly a twintercooler and that'll do for this car

like i said in the PM. Your power is bang on, why would you want more its pretty maxed out as it is. However id ask for the dip in power and torque spike to be ironed out and then you'll running a gleaming map IMO

But I like the spike :'(

I think it's partly due to the Decat. TBH I don't really see the problem with the spike as it doesn't dip much below the rest of the torque curve when it's finished and gets you moving.

torque spikes eat clutches. The only thing a spike is goof for is bragging rights. YOu can say you make 325lbft, but realistically your looking at 300lbft(which is still v.good)

I was thinking your flat spot between 2.5k and 3k needs sorting, because you can see the car is then trying to re-ramp the boost back up and playing catch up between 3k and 4.5k then you can see its finally caught up. You can see the indent quite obviously between 2.5k and 4.5k and id bet its due to the torque spike that its doing that. Probably cutting boost or timing to cancel out the spik, then it needs to play catch up.

I think if that were to be ironed out you would have an even wider plateau of power and more power in the midrange which in my opinion is more important than peak figures.

Mines decat BTW with no spike at all

I'll have a look at my logs later but before cooler and intake I had no boost drop after the spike had finished, just a nice smooth rise. I also had no timing pull until it started to heatsoak.

Looking at the graphs more closely it appears where I have the drop in torque @ 3700rpm the AFR leans out more than the rest of the AFR. So I believe this is a little fuel cut due to the spike using a lot of the fuel the pump is providing, The pump takes a while to catch up again.

An Rs4 FPR may fix this.

Did some logs tonight if anyones interested. Two consecutive runs, I don't really see any problems on the road.
