Nice video but you got scammed on the tune , no one pays extra for burbles it always comes with the tune , just like mhd ,you flash to the stage you want and change the burbles as you like as many times as you like.
Scammed is a very strong word for a company I have personal relationships with. MHD, BM3 ect are platforms where you can manage your own application. Modstock perform a different service without DIY functionality. I won both modifications during a karting race with Chris from Modstock and it was never in the bet to have additional burbles hence why I paid him extra.
