Stage 1 Driving Feel

  • Midrange: noticeably harder V6T torque hit
  • Boost: smoother twin-turbo ramp + cleaner pull
  • Daily: luxury-smooth cruising, violent when you want it
 

Crackle Pops & Overrun

Choose your sound profile. Subtle on stock exhaust, rowdy with aftermarket. Safety reduction if exhaust temps climb — won't activate until fully warmed up.

Frequently Asked Questions

 

Q: What mods are required for Stage 1?
A: None. Stage 1 supports stock hardware. An upgraded intercooler is recommended for repeated high-load pulls and hot climates.

 

Q: What mods are required for Stage 2?
A: A high-flow exhaust and front-mount intercooler (FMIC) are required. Intake is strongly recommended.

 

Q: Is Stage 1 safe on the stock turbos?
A: Yes. Stage 1 is calibrated around safe boost, EGT, and IAT targets with multiple layers of protection built into the file.

 

Q: What fuel does it support?
A: 93 octane pump gas.

 

Q: Do I need a TCU tune?
A: Not required, but highly recommended. A TCU tune improves shift logic, torque converter lockup, and overall power delivery. Without it, the ZF 8-speed may limit how much power you actually feel.

 

Q: Can I adjust crackle levels?
A: Yes. Low, Medium, or High levels available on request.

 

Q: Do I need a Windows computer?
A: Yes. The flashing software requires Windows. Mac is not supported. 50+ Mbps internet and 8GB+ RAM required.
