There not on the website, our website suffers from neglect. Its either spend time updating the website or we develope more cool kid stuff....;-) We currently offer the Holset VGT controller for 98.5-05 Cummins trucks. These are plug and play controllers that are infinetly tuneable to your setup. You can tune them realtime via a laptop and USB hook up allowing you to tailor the chargers characteristics to fit the way you want it to react. Its as simple as reading an Excel table and changing the closure percentage value of the vanes for a specified RPM and Fuel quantity. In the real-time tuning the cell the controller is looking to relay its demands for the turbo is highlighted in the table, so if it seems laggy at that point you can just punch in a higher closure percentage in that cell, save it, and it will immediatly adjust it. Clear as mud?
Our retail price for walk ins on this controller is $625 with the Exhaust brake option, but if you ask for Caleb and mention your on CompD when you call and order, Ill sell it to you for $595.
