I've noticed that from 140km/h my 2012 specv noticeably slows down and I'd like to know if it's normal.
Twice I got into a race against a 2016 civic si and I'm ahead up to 140km/h, then the si just keep speeding while
it takes my specv a very long time even just to reach 150 km/h.
I've modified nothing on it, 76000km, oil changed 2000ish km ago.
Thanks for your help!
