After several months of development followed by tests on dyno and in real conditions, here is the Precision EFI 850 E-TEC Stage 1 available for 2018,19 and 20. 
One of the most important improvements of the new reflash is the optimization of combustion, which eliminates the loss of power when the tune pipe is hot. A drag race  between a barely warm 850 E-TEC and a hot one running for more than 30 minutes, clearly shows a good difference.
Thanks to the new Precision EFI  850 E-TEC Stage 1, the sensation of weak acceleration is gone, giving way to a more stable and efficient power curve with a significant gain of 6 hp, without changing or adding any parts.
