2006-2010 Dodge Charger RT Flex-Fuel Conversion Kit
Convert Your 5.7L Charger HEMI to E85 and Increase your HP by Up To 12%
The Charger RT with the 5.7L HEMI V8 has a 5-speed automatic transmission standard. It also had a multiple-displacement system that was designed to save fuel by running on only four cylinders when cruising. That was a nice feature in the V8 and saved you a bit of money. When it came to horsepower the 5.7L HEMI had its fair share but for those who want more, an E85 conversion kit is the best answer.
No tuning required!

eFlexTuner Main Features
3D Fuel Maps
With eFlexFuel's Pro models, fuel maps can be observed in the 3D graphics window. The view can be rotated freely and selected fuel map cells are highlighted over the 3D map. The color-coded fuel map makes analysis simple.
Data Logging
All running parameters of the control unit can be captured and saved to a log file. Choose which parameters to display including date range. eFlexPro and eFlexMoto Pro log files can be analyzed in-depth with the eFlexTuner. Color-coding helps distinguish data points. (For example, the fuel mixture or the injector duty cycle.)
Log File Analysis
eFlexPro and eFlexMoto Pro log files can be analyzed in depth with the eFlexTuner. Data can be taken from an entire session or a specific timespan. The data is color-coded, which helps to distinguish e.g., the fuel mixture or the injector duty cycle.
