Frequently Asked Questions
Q: What's the difference between Stage 1, 2, and 3?
A: Stage 1 requires no hardware. Stage 2 adds a supercharger pulley, heat exchanger, and spark plugs. Stage 3 is a full dual-pulley build with TCU, intake, bigger throttle body, and all Stage 2 hardware.
Q: Do I need a TCU tune?
A: Highly recommended for Stage 1 and 2. Required for Stage 3. The TCU tune raises torque limits and improves shift behavior.
Q: Does it support E40 ethanol?
A: Yes. E40 support is available on Stage 2 and Stage 3. An ethanol content sensor is recommended for E40.
Q: Are these WHP or crank numbers?
A: All power figures are wheel horsepower (WHP) measured on BDT's dyno with transparent before-and-after runs.
Q: Can I flash at home?
A: Yes. 100% remote with live support. A Windows laptop is required.
