ECU flash and reliability?

Is there a difference reliability-wise between different flashes if the car is 100% stock? I would like to have mine flashed but I am afraid flashing might lead to issues with the car. Searching the forum some MAF problems may follow. Anything else to expect?

I'd not heard of MAF problems with flashes. I thought MAF problems usually followed exhaust changes (100 cell cats etc.) or air filter changes.
Mine was flashed 3 or 4 months ago, including new DVs and the filter was changed (but only for another panel filter). I've certainly had no problems with warning lights, and would be taking the car back if I did. The guys that did mine took time to take logs on plenty of times afterwards and make sure it had the right mixture.
In fact - from my research when I had mine done - I think that's the think you need to take care of. It's important that the map is right, and you're not running too lean. It's easy for tuners to go for maximum bang to the buck and come up with a map which will make you smile, but may mean your engine is running dangerously lean.
Not sure about Finland, but in the UK there are a few recognised specialists for this kind of thing. Although my map actually came from the States anyway (Promotive).

There are plenty of shops here that flash ECUs but I think what they do is just transferring software made somewhere else. I think that is ok if you have a Volkswagen Golf but I cannot trust my TT in the hands of such shops. There is only one here that I know that individually tune the software according to clients wishes. They also save a copy of the original in case customer wants the original software returned.

This is what happened with mine. The local specialist doing the work used Durametric to log how the car is running with / without the map, and adjustments can be made by the remote tuner based on those logs.

When I bought my TT, I found that the PO had purchased a Flash for the ECU. He bought his from Softronic Tuning. Read the FAQ on their website. That should answer most of your questions. Other than that, you can call them, if you want. They were really ready to answer my questions, even though I didn't buy it from them.
