| is really held back by the single. Can you get a before dyno pull the same day and install it at the shop? (if you were intending to dyno that is) I'd love to see a clean back to back on this one! My only concern is that you are basically already using all of the measurement range for single pop or Selin dual MAF in ADD mode... The improved flow of the dual intake could easily put you over so I'd get the dual pop program at the same time to be safe. The last thing you want is to run out of metering at the top of your powerband especially if you aren't monitoring your air fuel ratio.
