Hey @Stralec
You've got to make sure you follow the update scale when you spend your initial 50 TPE.
0-50 - costs 1 TPE to go up 1 point
50-70 - costs 2 TPE to go up 1 point
70-80 - costs 5 TPE to go up 1 point
80-90 - costs 10 TPE to go up 1 point
90-100 - costs 15 TPE to go up 1 point
So to get speed from 60 -> 73 for example would cost 20 from 60->70 and then 15 from 70->73
