Just fitted a Unichip and 4" Rear muffler to MY01 from APS.
UNBELIEVABLE!!!!!!!!!
What a difference it makes.
117Kw at the wheels..........up from 90Kw.
The exhaust note is superb and makes driving that much better, not to mention the heap of torque on tap.
Bottom line
AUD$2,300
29% increase in Power (Kw)
30% increase in Torque
QUESTION???
Does that mean that 160kw as std goes up 29%.......then I have a 206kw car?
Can some tech head out there answer the above....
I'm dying to find out.
Unichip rocks!!!!!

G'day Baagwan,
Was the brand a Dyno Dynamics rolling road. If so, it is the same as APSs and also my m8s one, Croydon Autosports, who is also an APS dealer, back in Sydney. From memory cars with 117kw at the wheels are probably closer to 195 to 200kw at the flywheel. APS in the June edition of Modern Motor mag tested 2 version 6 STIs and a version 5. The three were stockers. One version 6 got 129kw at the wheels, the other, 123kw @ wheels and the version 5 got 126kw at the wheels. These would be closer to 206kw at the flywheel. My m8s dyno used to get the same power at wheels for the stock STIs. Also the stock 160kw rexes were like yours at 90kw at the wheels at Croydons dyno.
If my assumptions are correct, 200kw is huge power still. Not far off the 206kw.
Hope this helps,
Cheers,
Wrexy.

If only I'd been able to read your thread at a time before I went on my hols cause I have an MY01 and have just come back from Melbourne where I was for 2 weeks. Tend to go out every 2 years so maybe meet up next time
edited to say $45 000 for a new WRX (from a dealer at Frankston), ours are $57420 at 2.64 to the pound. I'm envious.

Big help thanks...
I thought it would be around 200kw or so..
Such a huge difference to the car....I'm still driving around with a grin from ear to ear.
I don't know the brand of dyno......other than it was done at APS in Bayswater....
GOES LIKE STINK!!!!
Mr Zoidburg
yep $2300 fitted....
got a discount coz i belong the wrx club ...100 bucks or so.
the 210 Kw RT spec....
I think its about AUD$5,000
bigger intercooler and a complete exhaust...not just muffler...
BUT ,.,..think about the insurance...& warranty
I reckon a chip and a muffler shouldnt trouble the insurance to much.
The mods I made are worth every cent.

APS in Bayswater, which is the central APS dealer/distributor in OZ, do have a Dyno Dynamics rolling road. That is where those STIs were dynoed for Modern Motor. APS do seem to have nice, go faster kits for the rex.
Enjoy your car m8!!!

hey, Wrexy - you've absolutely made my day (make that made my year 
).
went to the trouble of making the 8 hour drive to Possum Bourne's workshop in Auckland to have my recent possumlink-fitted WRX tuned and dyno tested.
Possum Bourne's have just installed a Dyno Dynamics rolling road.
Happy with the before and after comaparison on the graph - but power output showed as 128kw.
Hell, the car's advertised as being 160kw stock standard.
WTF?
Since the dyno test it's niggled me about the car having 'low' performance even tho' the car burns off everything in sight on the road.
However, you seem to confirm this thing about 'at the wheel' and 'at the flywheel' readings.
From the figures you quote above it suggests I'm achieving ?210 - 215 kw?
EEEEEEExcellent !!!
And whilst I'm at, can't understand the torque figures, either; the column on the graph is headed 'N' (is that Newton somethings?)
and the reading on the graph is 4800.
Can't see anything in the dyno threads that this alludes to (the scale on the graph goes from 1000 N to 9000 N)
Can u enlighten?
all the best
- oh and btw to b5m; the turbo boost was increased from .75 to 1.1 bar (that's about 16 psi - if I've got the decimal point in the right place?)

Philc,
That's very impressive. Great figures. Lots of guys are getting good power gains from the Link ECUs on this bbs also. Bob Rawle seems to be doin' a good job with them in the UK.
The tourque figures are in Nm (Newton metres). The 4800 reading seems to high to me. It should be closer to around the 3000 mark. You are probably looking at the power (kw) graph line which is the top one. It is the second lower graph line you should be looking at. Normally the Nm torque figures should be with one less zero than the graphs show, for eg if you had 2900 on the graph it means 290 Nm. I'm not too sure why it is displayed like that and with just the N and not Nm, I've been away for a year and a half so I have a bit of catching up to do.
If you want to compare some dyno figures from a Dyno dynamics dyno in OZ have a look at this link. It's my friends one at Croydon Autosport in Sydney.

thanx for the futher info wrexy (and apologies for hi-jacking your thread, bugwaan).
yep, the graphs on the url u posted, wrexy, are the same layout as the one I have, except at the bottom (?y axis) it's in rpm not kph.
and there are four lines on the graph, two in blue and two in red; the blue being before tune-up and the red being after tune-up.
the lower two lines I was told are the torque reading, with the red one peaking on a curve at 4800N at about 4500rpm.
now, I do my conversion to lb/ft so I can compare with the scooby site dyno charts and it's 354lb/ft - and there's nothing on the scooby dyno listings that's close (there is one STI4 reading 340lbs/ft).
hence, on the one hand I'm really rapped about this, on the other - is the figure believable?
I certainly told the tuning guy that I was more interested in torque rather than straightforward power and the car accelerates frighteningly fast in second gear.
so maybe 4800 is right?
(I'll post the chart next time I get to a scanner).
Whatever, extremely grateful for your input
regards
