Understated by design, not by capability. Our SHO recalibration makes better use of the 3.5TT’s broad torque curve and tightens 6F55 behavior, turning the big AWD sedan into a quicker, more coherent version of itself.
Engine and transmission
- 3.5 EcoBoost, 6F55: $600, or $1,200 with Custom OS
PCMTec software can adjust much more of the factory PCM than alternative software can. Every file is written for one car with longevity in mind. Acceleration and response improve, the car stays smooth and consistent in all conditions, and the factory safety systems and drivetrain protection keep working, whether it is driven every day or run at the strip.
Transmission
- Converter and clutch. Less unnecessary slip, so less friction and heat and more torque holding capacity. Power delivery feels more direct.
- Shifts. Faster, more predictable gear changes under load, with pressure curves profiled so light throttle stays smooth.
- Adaptive learning and KAM. Realigned for the higher torque, so the transmission keeps adapting correctly instead of mislearning.
- Torque truncation and spark cut. Recalibrated to protect clutches and shafts with as little interruption to acceleration as possible.
The recalibration starts at $600. The PCMTec Custom OS is $600 on top of it.
