you yourself said you are a noob when it comes to these cars, so let me help you out. the current record holders for the most power out of both speed3 and speed6 were untuned and simply using a map clamp/bcd and a manual boost controller. i would venture to say that more people have popped using some form of ecu tuning than untuned.
if these engines are not prone to failure, then why are there "blown engine resource threads" more than a few pages long. maybe not on this forum but on others. if these engines were so stout, then why havent more companies hopped on board making parts? 3 years after the engine's inception, we have one proven race team starting to take a good look at us, DCR. if these engines were not prone to destruction, why would we even be having this conversation?
do the math. take the number of blown DISI MZR motors + the amount of recalls issued for factory defficiencies + the amount of TSB's concerning major parts of the car (ie high pressure fuel pump, turbo seals, clutch, pcv system etc)= not that great of an engine.
dont get me wrong, i love my car. but to think that the engine is stout, mod friendly, or extremely reliable is just naive. i bought my car brand new in 06, and have been on the forums since then. i have read just about every thread concerning these issues. perhaps you should go back and read some more of the success and failure threads before you tell me not to speak out of my ass.
