+points

Hopefully the answer to this will be straight forward. I have 83 points for acceleration +14 so it shows 97 on main screen. It give me option to go above 86 points, does this give you better performance than 100 albeit only shows 100

No just wasting the points

Hi Matt
Just go to 86 points. any more and yes your wasting them as if you take it to 90 points it will still only show 100 on your screen. Now if you change engine supplier or fuel supplier then yes you need to put more points into acceleration to get it back to 100

 Something I should really know by now, thanks for heads up.
