This is why we love working with KC Turbos so much, Charlie is so data driven! Working with AMDP, we spend days, weeks, sometimes months on and off testing finding little tweaks here and there, at varying loads and conditions, both on and off dyno, for the next updates to be sent to the customers. Its the endless chase of the 'perfect file'. The results always end up with real world gains, new versions better then the last. Cross testing year packs and applying changes to make sure each year pack of truck will run the same as the next. Its alot of work, and very rewarding when the feedback comes in.
On a side note, we also have a slew of videos and cool data coming up for the 2020+ KC turbo release! We have been absolutely loving it on our 2025 F450!
AMDP Tuning + KC Whistler 6.7!
This dyno graph shows how much tuning strategy alone can change the outcome on the same truck.
All pulls shown are from the same 2012 truck running a stock 15+ CP4 and a KC Whistler Stage 1 VGT turbo. Fueling was kept the same. The only variable changed was the tune.
Color breakdown:
• Yellow: Competitor A
• Green: Competitor B
• Blue: Older AMDP calibration
• Red: Newest AMDP calibration
The difference comes down to VGT control. How the vanes are driven directly affects airflow, drive pressure, and how efficiently fuel can be used. Better vane control opens up a larger, safer window for fuel control without relying on excess smoke or harsh drivability.
What’s shown here isn’t a “turn it up” approach. The newest AMDP update reached the red line result using the same total fueling, with less smoke and improved drivability compared to earlier files. That’s the result of iterative testing, data logging, towing, elevation testing, and refining strategy rather than chasing peak numbers.
This is also why updates aren’t rushed. Real progress comes from spending time on the dyno, reviewing logs, making changes, testing again, and repeating the process until the combination works across real-world conditions, not just during a single pull.
