Turbo Time USA Lightning Bolt VGT Solenoid 03-07 Ford 6.0L Powerstroke

While some may have mixed feelings about Variable Geometry Turbos (VGT) they have a huge advantage over their fixed geometry counterparts in that they can dynamically adjust their "size" using an internal moving vein or a sliding nozzle. What this means, is that upon takeoff, the turbo can act like a smaller charger, but then open up as RPM and boost increases, delivering the airflow of a larger turbo. Beyond this, another big advantage to these kinds of turbos is that they can essentially be "tuned" due to their electronic solenoid, and up until the point where Turbo Time USA developed their Lightning Bolt Performance VGT Solenoid......no one had done so yet. The Lightning Bolt Solenoid is designed to help you get the most out of your turbo (especially upgraded turbos) and diesel driving experience without artificially manipulating your system to operate more like a gas vehicle. Forcing a diesel to perform more like a gas vehicle is often experienced with products like throttle controllers, modules, or specific tuning that alters VGT vane percentages and/or causes the transmission to regularly downshift raising rpms to achieve power response. Some of these application combinations may reduce the effective benefits or even conflict with the Lightning Bolt Solenoid operation triggering a CEL.  NOT recommended with products like “pedal commanders” or “throttle boosters” that manipulate throttle system percentages that often yield an artificial “in the seat” response feeling while reducing efficiency.  NOT recommended with tuning that restricts VGT vane percentage ranges and/or causes the transmission to downshift when applying throttle for demanded response by increasing engine rpm instead of utilizing low-end boost production from the turbocharger in order to generate power as originally intended for diesels. TUNING - Some tuning especially with emissions may manipulate the vane position percentage range that can conflict with the Lightning Bolt operation which is intended to operate with full range. This can lead to a CEL and trigger codes such as "over-boost" or "exceeding learn limit".
