Sprintbooster issues

Did anyone else with the Meg conversion have any intermittent 'lose of throttle problems with the sprintbooster fitted'? I did so sold it on. However, I kind of miss that instant throttle response you get from it which is so much better than simply pressing harder on the loud pedal.....

Whats interesting is I cant find one person who has one fitted on Meganesport. Its the same part number.....
 
I had problems saying "Injection fault", and the throttle wouldnt work. It turned out one of the pins had bent while installing it. I took it out and straightened out the pin. Now ive had no problems what so ever.
