/\ Yep, more pointless 'bigger is better' nonsense, which it isn't.
For everything you change up in the mid and top ends, affects the bottom end and idle....but people just quote peak hp don't they? Never the bad stuff.
1.8T is not TFSI. Fit a bigger plate and you'll need to retune the hot and cold idle, over run, VVT, hot and cold part throttle tip-in/out, hot and cold full throttle tip-in/out, part throttle cruise, in-gear roll up to a stop stall conditions, pedal ratio, all of it! All the tricky stuff to tune. WOT is easy.
I appreciate a lot racers don't care about traffic manners, but having played with big throttles and having the luxury of a standalone to make the above changes myself, I'm not going back there again. Not worth it for 5-10% gain in an rpm area seldom used on the road.
What would be more useful is that throttle in stock size, to fix reliability issues with the stock part.....although having said that, TB failure is rare, more so after the Q revision. 57mm is appropriate for a smooth response, and it's a boosted engine. 70mm is VR6 size and not appropriate for a 2.0.
