when i fitted it, i only went a mile home from work. and after a few days of just driving, and the car being fairy new (had her 8 months nowand 3 at teh time of fitting) i was still getting used to how she drove i suppose, even more so when WOT! so with the spacer on she felt strong.
but now ive taken her off, certainly when WOT there is a difference!
if not on boost though, i would say their is minimal difference. 4k onwards to the redline it IS noticeable!
anyone with one still fitted, do a few WOT runs take it off, and go again.
