am confused about the ECU Upgrade !

some say if u upgrade ur ECU u will get 30% - 50% increase in boost and speed limiter is removed (Blitz ECU Upgrade)

Speed Jumper (removes 112mph limiter) so what is this then ?
only removes speed limiter no increase in power ?

which one should I go with ? ECU Upgrade or Speed Jumper ?
