I'm letting everyone else be "beta" testers first

No sense of adventure, eh???

For me the question of having upgraded engine internals is purely subjective. I would like to think they are being used, but as my engine is still standard and has the increased power over a standard GTI anyway, it doesn't matter.
That is so true, and a major point of view which we have all missed!

I'm certain that whichever engine you have (the standard GTI, the Ed30, or the Cupra/S3), providing you don't modify it, maintain it appropriately, and also treat it appropriately - then it will be absolutely bullet proof.
When it will matter is if and when I do decide to upgrade the power. I may now only do this once a definitive answer to whether the internals are upgraded is settled.
I don't think that sensible, modest power gains from chip tunining or other methods will be problematic. I would be reasonably confident that adding an extra 30-40% increase, on whatever engine, should be relatively safe. Therefore, if you have a standard GTI, then taking into the realms of 280PS will be OK, for an Ed30 motor, upto 310PS, and for the S3 upto 370PS.
I see problems when people with the standard 200PS GTI lump try to match the 370PS figures of the S3 engine. If that
is your preference, make sure you carry some chicken sh!t and a tow rope in the boot!
