We are getting increased stock boost by 3psi via BMS for $500.

Yeah but its a big difference between writing new timing and fueling tables for the boost and tricking the car into running more boost. The former will always be safer and more consistent if done well. For instance to run 3psi with the BMS you have to run race gas bc thats beyond the ECU's amity to adapt fueling and retard timing. It also allows you to do something the BMS can never do in its current state , add power up top more than in the midrange (assuming the turbos are not maxed out) I don't want any more low end torque, i can't use what i'm making now lol. And if they are the only ones to crack it after working countless hours on multiple development cars that they purchased , charging 2500 -3500 is totally understandable initially. Terry had 0 development costs for he BMS on the M5/M6. Dinan has put several hundred thousand into by now. Its not like they would be selling a development file for 2500 like everyone else has been .
My two cents
