I have brought a manual boost controller which can be seen in the link below. http://www.lindseyracing.com/LR/Parts/TECHMBC.html It has 4 ports and I've had it setup with only 1 port blanked off and then one going to atmosphere. Having found this installation guide, There is no atmoshere blow off- so do I not need this, and have 2 holes blanked off and set up as in the 2nd picture on the link?? Cheers
