actually...... I PREFER no vacuum pulloff on my fpr... just spring pressure set to 40 psi.

The reason... During cruise driving, the ignition map tends to be running high advance(for economy) and with part throttle, there can also be a high vacuum. High vacuum on the FPR, and significant ignition advance can lead to running lean, and causing pre-igniton(ping) while at part throttle.
