For the past 3 months, I've been running water/methanol injection on my GTi. Lets start with the basics:
- More HP and Torque
- The car hauls from anywhere
- Cleans the cylinder walls
- Cools your intake pretty nicely.
- The methanol serves as an extremely high octane fuel, Its better than race gas because when you are idling or just cruising ur burning all that race gas. With w/m injection, you can turn it on only when your car is under load.
- Allows for more timing
- My homemade kit cost less than $200
- Very hard to find methanol (I buy tons of HEET(the yellow bottle) and distilled water. Recently, I've been buying Valuecraft -20 nd add a bottle of HEET to boost the Methanol ratio)
- I've got a relatively big nozzle so you go through the solution very quickly. The washer reservoir has a capacity of 1 gallon I think.
I put in about $145 into this (the pump, nozzle, etc). My uncle gave me a pressure switch (those shouldn't be too expensive). Those are the 3 big things. All the rest includes tubing, pump fittings, wiring, mini-clamps, relay; you can find these very inexpensively. Altogether, it was way less than the $470 Snow performance kits, or the $300 something devils own kit. I've got a vid below on what the whole mounted system looks like. Enjoy
According to G-Tec Pro: 258 HP at the crank (226 WHP) @ 40F ambient temperature.
I'll post up some data logs with the meth kit later on.
Back in December, I got APR software for my GTi, and all I have to say is wow. Power is smooth, and coupled with DSG, it is an amazing feel. Based on APR, numbers are about a 40 HP gain with about an 80 ft/lb increase in torque, with just the flash. For anyone thats sceptical, APR offers a 5 hr trial for anyone to test out what 250hp and 300ft/lbs of torque feels like. With APR software, the stock 12 psi is bumped up to 20psi (at least thats what I'm boosting at).
I'm very impressed at how well APR software works with DSG. DSG fully adapts to the large increase in power very nicely with the software. There are no hard shifts or stalling of any kind. Shifts are stock smooth and still lightning quick. Also, you still retain launch control after the flash. APRs software comes with free lifetime updates (if knowledge serves correctly), and there are different flashed to accomodate different mods.APR has a few different "stage" flashed that reflect certain aftermarket mods. To use APRs stage 2 flash successfully, you need a downpipe. The software for stage 2 accomodates for the downpipe, and you see appropriate gains.
For the time that I've had APR, I've been completely satisfied. They have amazing customer service, and you can get valuable info from reps on different forums. Adrin@APR on the Vortex is a very helpful and educated person. If you have a question ask him.

VAG-COM coding is a a very sensitive process, and things can go wrong very quickly. Coding that contradicts something can cause a whole process to fail. Be careful before you modify coding, take precautions like copying old coding before you modify it. I suggest reading online info before you jump into doing coding.

My uncle owns and distributes HID comversion kits, so I get all my lighting mods free :D. I've got some 6000K replacement bulbs for the headlights (since the car comes stock with HIDs), as well as 8000K fog light conversion kit. I decided to help out my uncle and make a sort of promo video. Its the least I could do, considering I get free samples. Hope you enjoy the vid.
By the way, check out his site: http://www.gothidxenon.com/

If you guys have any questions and stuff, email me, I can try to answer your questions.
