TFSI is stronger than the 20vt but its high cr high boost direct injection jobbie so bad mapping will kill it fast.
there are modifyed exampels relialy kicking out 400 - 450 bhp reliably
they mentioned other components that were weak, cant remember what but they have had a load back on non modified cars, so anything tuned is gonna be fragile
they say the Bam/Amk engine from the 20VT range is the one to have, iv got a AMK.
i dont know much about it all but im only looking for 270hp, i liked idea of the newer TFSI coz you can get them cheaper than a Bam/AMK and the miles are still low on them.
As luck would have it, i managed to find my AMK with less than 40k on it - perfect..
