WAMS is now proud to be the only company tuning the 05/06 G6 3.5L with the P05 controller.
Here is a highlight of the 100+ changes made to the G6 3.5L PCM
• Proprietary extensive fuel and spark mapping for high octane fuels. (Premium Fuel Recommended for best results) Unless of course you opt for the 87 octane version.
• Revised torque management settings allow the 3.5L to get mroe power to the ground.
• Shift torque managment recalibrated to allow the engine to actually keep some timing in during shifts, the stock calibration had negative timing on some shifts.
• Beta and end users report a significant increase in fuel economy (2+ MPG); your mileage may vary. (91+ Octane calibrations only).
• Raised rev limiter to accommodate the engines new power band (6300 RPM)
• Top Speed limiter completely removed.
• Fan turn on points adjusted slightly for more power and better fuel economy.
