Looking in to the future when my GTi PP arrives date TBC, was keen to extract a bit more power from the old girl.
Anyone had any dealings with a tuning box?
Reading on their site & as they are local they offer try before you buy option

Go for it, with the try before you buy option. I'm looking at one of these for a Volvo V40.

I'd give TDI-tuning a wide berth. My first foray into tuning boxes was with my MK7 GTD. One of the first companies out there with one for the GTD was TDI-tuning, so I got one.
The car ran like a bag of hammers, the frequency of my DPF regens more than doubled, my mpg dropped right off and the power delivery was brutal and crude.
I sent it back with my misgivings and they "tweaked" it. In effect they cut the power right back, making it pretty pointless.
I gave up on tuning boxes for a while until DTUK brought one out. They were local, so I paid them a visit and tried before paying - the difference was like night and day - lots more power, delivered smoothly and no negative impact on mpg - the frequency of my DPF regens halved vs stock.
Andrew at DTUK gave me the opportunity to get involved with the develooment of settings for his new "Trevor" box, and I saw just how much development goes into his products.
I know your car is a petrol, so some of the considerations won"t apply, but i'd put more stock in DTUK than TDI-tuning for the reasons above.
If you look at the TDI section around Jan 2014 you'll see my comments on the tuning box saga.

Currently running a DTUK tuning box on my PP.
All I can say is get one - you won't regret it!!
Absolutely no issues and always had good customer service from DTUK.

The multi channel one?
What sort of gains did you get as can not see any figures quoted on their site :(

I'd buy the DTUK one, with the Volvo i'm scrambling about trying to get the cheapest option(which aint the best) to try and give the car(it aint mine) a kick up the ass.

I would only consider a custom rolling road remap from somewhere with a good reputation. Personally.

Yes, the FSR+
Never had it on a dyno myself but it's a hell of a lot faster with the box - fast enough for me to happily believe the figures I've heard. Might be worth pinging an email to them as they will give you an honest reply.
Just did a quick selection on their website to get to this page...

They quote 316PS (311.6 BHP) on their website for the PP car.

Thanks Gnasher.
I have also been speaking to Superchips to as the bluefin looks like nice sensible gains to with a nice power graph to prove...

I've got the bluefin from Superchips and the DTUK pedal box great combo. Like the Bluefin as i can take the map out and in as needed.

This is alos why I like the idea of it.
I spoke to Bluefin/Superchip as I questioned the std figures shown on their dyno graph there response was...
"Thank you for your enquiry.
The power graph on the site is correct - we always publish exactly what we find on vehicles. There's even a video of the test car! I've yet to see one of these 220PS or 230PS VW engines make less than 250hp on the dyno, and we've seen Golfs, Octavias, Superbs and A3s with this setup. You will note that the non Performance Pack cars makes equally high figures as stock. It's just how they roll on our dyno. Check out vehicles like the latest Mini JCW - similar sort of thing, more power than the manufacturer claim as stock, whereas the new Range Rover TDV6 makes a little less. It's mainly due to the nature of running a car on a chassis dyno - it's not the same sort of test the manufacturer do to create a horsepower figure. This is why we publish what we find - to prove we've seen a car, and to point out that it's the *gain* that's important, not the absolute power figure.
Kind Regards"

Originally DTUK also found that standard engines produced well in excess of the manufacturers figures too - so I don't reckon either were lying.
The figure to take from anything is the increase - that's the only way to compare like with like. I think that increase is very similair to the increase claimed by DTUK.
-
Having owned both a PP GTI & an R I can well believe the various rolling road prints I've seen showing the standard GTI (vRS etc) putting out more than the published 220/230 PS. Once run in the engine feels much stronger than the figures.
I'd also say that the R only just makes the claimed figures but is still very noticeably quicker than the various GTIs I've driven in the higher rev ranges.
I've had a DTUK tuning box and a JB1.
I prefer the JB1 but have to say the DTUK is better built and far easier to adjust.
The JB1 scores on the finite adjustments you can make, particularly if you have further mods.
Once the JB4 gets released it will be a game changer for VW group add on boxes.

the GTI 220ps that we took to the dyno was 259hp stock, and 314hp with the FSR+ on map 3 plus 2.
We've since had a customer with an S1 take his 231ps (claimed) to the dyno, and his car was 260hp stock, and 316hp with the FSR+ module

Thanks Andrew I am leaning in your direction once the car arrives :)

Out of interest, why would real cars seemingly regularly exceed the manufacturer power output figure frequently?
Doesn't make much sense does it?

The most plausible reason I can think of is that they come out of the factory with a minimum of the stated PS output. Of course you'll get variation (probably all within 5% of each other as they come off the line), but if they're well run in they have even more potential.
My R feels a lot stronger than it did at new, people talk about their car being far better as the miles go on, but with 7 TDIs bought from new, I never saw or felt any appreciable gains. The R seems to get better and better.
I'm assuming mine has been well run in from the economy it gives even when clogging it - with a heavy right foot i'm still seeing 82% of the official combined figure on my 20 mile commute right now. A lack of oil consumption is also usually a good indicator that the car is well run in.
A test of run-in gains (or lack thereof) could be proved or disproved by dyno-ing some factory fresh ones (preferably at least 5 to account the natural variation) and then again at 1500 miles and perhaps 5k miles.
Anyone clocked a GTI pushing out 250PS+ straight from the factory on a Dyno?

Rolling road lottery :whistle:
How the car is strapped to the rollers, tyre pressures, atmospheric pressure, ambient temperatures, cooling fan size for the dyno, is it in an open or enclosed space, can all have an effect on the power the car produces on the day
For example I have a customer with a Stage 2 Focus ST (2.5 model) which should make 265bhp all day long
He went to a rolling road day and made 241bhp. Another ST with the same mods but different map, made 281bhp
They found a 'private' test track and nailed it. There was no difference between the cars on the road :whistle:

Dyno operation seems a more likely contributor to these variances.
A car running almost 40 HP above manufacturers stated power does sound a bit suspect. Tuners often use high headline figures for sales anyway.
I would have thought a mass car manufacturer is capable of achieving desired output as measured under whatever conditions they use to within a few %.
You often see talk on forums of certain cars being touted as always making above the manufacturers claim with limited evidence that this is the case.

There are many factors that influence what manufacturers claim as the (minimum) power output of the cars. Insurance grouping etc. are among them. Maybe VW are quoting figures 'out of the box' that the car can produce and this goes up as the car loosens up.
For whatever reason, there are some accurate dynos (with people who don't have a vested interest in what the figures are) out there showing that the cars are producing above the manufacturers quoted figures.
But then again, VW do have a reputation of underestimating figures, be it power output or emissions lol.
