That's the tuning kit bonus, before the update it was 10% while it should have been nearby 27%. Earlier my 1591 went at 454 with tk, now it goes at 467kmph..

I also dont have the another 20 custom engines, got 6 of them but I am not upgrading it right now. But many players have already pro'ed it already, they might have won engine cards in Test drvie cups.
