Title: Powertune duals
Post by: Farm boy on December 16, 2018, 09:33:04 AM

I know a 2-1 is the best for bottom end torque. My question is, will the powertune duals have the same bad dip, as true duals ? :nixweiss:

I'm pretty sure the power tune duals are the same pipe as the Cobra Power Port headers.  Herre is my dyno sheet on my '12 CVO SG.  Stock A/C with K&N filter element, Andrews 57H cam.  Not much of a dip down low.Edit:  113 CI from Shamrock n Round Rock TX.

was the tire slipping on the dyno?   If not you may want to add a VPC to the clutch as it is showing some slippage look at the line where they have a upside down hump
