The BMS tune has MAF control so it won't trigger warranty detection codes. Has solenoid control for cars with the pneumatic solenoids for smoother boost control. Has a laptop interface which lets you do datalog and enable race gas mapping that has even higher boost levels. And the BMS tune will have a Stage2 upgrade box out some day that connects to the Stage1 tune and adds even more hp, wheel controls, in dash gauges, etc....
