Line pressure. WARNING, only designed for built transmissions. The factory transmission pump is
NOT designed to be run more than 165-170 psi of pressure. Our current overdrive tune sets these
values to 170psi (the pump mechanically will not supply more pressure, and will build excess heat
and waste energy). If they have a modified pump, they can use this adjustment to increase clutch
holding pressure. We have tested up to 250 psi with great results.
5 levels:
1 – stock 160 psi
2 – Default 170 psi
3 – 200 psi
4 – 225 psi
5 – 250 psi
