I just bought a 98 with V1 S-trim non-intercooled. It's only making 5psi. Can I pulley it to 8psi with the tune that came from Vortech? What if I also swap to a power pipe? Retune required?
..... when in different weather the blower still spins the same rpms and the computer makes the timing changes for the ait's change.
Yet colder weather or lower altitudes INCREASES boost levels too, right?
