PCM Module

ZZPerformance offers reliable support, fast turnarounds, and prompt core refunds with this product. This PCM upgrade, when combined with a tune, can yield significant gains, with typical results around 40whp and 80 ft-lbs of torque. On a chassis dyno, expect figures nearing 280whp and 320-340 ft-lbs, though torque output is managed to prevent slippage with stock clutches. The PCM is configurable for various sensor setups, including stock sensors, optional GM Stage 1 sensors, or a combination of both, with options for plug-and-play adapters or direct wiring. Compatibility extends to the F35 5-speed and F40 6-speed transmissions. For those with the F40 6-speed conversion, the PCM can be tweaked to ensure accurate speedometer readings. The tuning can also be adjusted to reduce first-gear boost for improved traction or to increase it for quicker response with upgraded clutches. Relocation of the MAF sensor in the lower charge tube as a "Blow Through" design is recommended for aftermarket intakes and blow-off valves to prevent poor running conditions. ZZPerformance provides remote tuning support via HPTuners, with an optional $100 deposit for advanced troubleshooting. Various core charge options are available, including sending in your original ECU/TCU first for flashing or receiving a pre-programmed core. Note that the core charge option is not available for Saturn models. Custom swap options are also available for vehicles not originally equipped with the LNF engine, such as tube chassis, sand rails, or engine retrofits.
