so far my experience jumping controllers to controllers
turbo smart , stable , dual stage , easy to use , simple
avcr , advance , complicating , stepper motor
dsbc , i dint like it , to change to diffrent boost setting u turn the button , halfway on the highway having a war , turning a knob isnt my style , its summore so small. although u have 4 boost set n one scrabmle boost, dbsc is using dual selenoids
currently im using profec a spec II , very simple settings, no advance function , bt its all tht i need , beeps n flash on overboost , 2 seetings , hi and lo , just press a button for next level boost. this one uses a selenoid also , if not mistaken single
