Choose this option if you will NOT be using a wiretap tuning module that adds timing. This is a custom tune built for your build that includes aggressive timing and CANNOT be paired with a wiretap module that also adds timing or engine damage may occur. This tune allows more fuel, more timing, and more rpm than any non wiretap tune ever produced for a VP44. It can be paired with a fuel only type wiretap for all out performance and peak fueling at high rpm to the limits of your pump PSG. Automatic and manual transmissions supported. The SO VP44 is limited to 3800 rpm. Without wiretap the SO VP44 PSG will begin reducing fueling near 3500 rpm. More than 3800 rpm is possible when paired with a performance VP44.
