In the usual way throttlebodies give an engine more power at higher revs. Also the torque is more at a higher point and more concentrated at a peak.
So if you‘re more on the torqueside and cruising, a testdrive would give you the answer. A „flashed“ GDI is a nice thing on twisty roads,
you can keep it very fast in the same gear only riding on the wave of torque.
