It\'s a long time since I ran twins but from memory the standard boost pattern for twins is 10-8-10 (psi). So you should see 10 psi up to the turbo changeover point (4500rpm?), a slight drop as the turbos changeover, then 10 psi up to the redline. I\'d guess with the filter kit and exhaust it\'s probably boosting slighty higher than that, maybe 12-10-12. If it\'s doing more than that, especially up to the redline then drive it off boost until you get your mapping sorted. IMO it\'s well worth saving up for a PFC.
