Sorry for posting that twice.
Zoheb, as I said, it is the Car and Driver magazine, published on Feb 2005. They called it a "Comparison Test - Mitsubishi Lancer Evolution MR Edition vs. Subaru Impreza WRX STi - THE REMATCH". The article starts on page 60 of the mag and ends on page 71. I did not get the article from the net, I have the actual hard copy of this magazine, purchased from Malaysia on my visit last month. And, I don't think its an Asean Edition, it is priced US$3.99, UK£3.20 and Canada $4.99. If you still have doubts, I can fax you a copy of the page in question if you can give me a fax number. Or, I can try to see if I can borrow a scanner from someone to e-mail the concerned page to you.

1. I am running an external wastegate - which is controlled by the boost controller.
2. It was tuned on our pump fuel and on our roads. I had the tuner flown in from his country of residence. The computer had a base map in it tuned for 91 ron fuel. But, as I said above, the fine tuning was done in Dhaka after the engine was installed.
3. The tuner carried a portable wideband air fuel ratio meter with him. The o2 sensor was attatched to the exhaust via an exhaust clamp. A large digital display was attached to the windscreen. It was a serious piece of kit. I was doing the driving while he was doing the tuning. Though, he had to do some driving also. I know it is ideal to tune on a dyno, but what could we do here ? I would have kept the air fuel ratio meter, but it was just soo expensive - and the o2 sensor gets fouled very quickly if you keep it on all the time. There is a cheaper wide band meter out in the US, which I will go for. You probably know that narrow band o2 sensors are useless for tuning.
4. The fueling is set to run rich in the higher rpms - too rich for my liking but he wanted to minimise the risk of engine damage from a bad batch of fuel - 11.9 to 1 if I can recall (?).
5. The computer is an aftermarket unit that comes with a hand controller. I can alter the fuel and ignition maps myself. So, if I had race fuel, I could advance the ignition timing to get more power with the hand controller. But, before I do that I'll need to get the wideband sensor/meter.
The brakes are 6 piston with 378mm (14.90 inch) disks. I don't see the point of the mods unless you can stop when you need to !
Hope this answers your questions.

Check the link below. Or, you can go to the Car and Driver homepage, click the link to "Ultimate Comparisons", then click the link to "Bad-Boy Sedans", go to page 4 of the article - and 'voila' - you have the performance figures. Now, if you still can't find it, let me know.
