The Story
Factory solenoids in 68RFE's installed in 2007.5-2010 Ram 6.7L diesels are prone to circuit boards flexing and bending, which leads to false pressure switch errors. Even with dedicated tuning of flow rates and pattern control, you're still going to have issues with drivability. SunCoast has performed thorough testing to identify means of correcting this issue and the answer is simple. Buy an OEM solenoid pack to install with your build.
