Ok guys and gals, here it is!! Tuning for the 450 is ready. HUGE gains on this little machine! Check it out and let me know if you have any questions other than when is the 570, 850, and 1000 tuning going to be ready. :biglaugh:

570 we had to make a few changes to as the tuning is much different with out being fly by wire. Should have it very soon!!

Here’s the details and a pic of the stage 1 final dyno run. Thanks for being patient with us!! It takes a lot of time to do some of these tunes and reliability and safety are our number 1 concern. Pricing starts at $449 and goes up per stage.

Speed Limiter Removed
•Rev Limiters raised
•100% Throttle opening vs. factory 30% limitation
•Improved throttle response in all modes
•Improved ignition timing advance optimized for 91 Octane for maximum power on stages 2-5
•Fueling adjusted for aftermarket components (intakes, exhausts) for optimal Air/Fuel Ratios
•No need to run a "piggyback" fuel controller with our reflash for most bolt on mods (You are responsible to make sure your mods are compatible with our programming – Most aftermarket companies’ exhausts and intakes are compatible with our programming)
•Torque Limiters removed for a much more responsive and fun vehicle
•Cooling fan on temperature is lowered by 20 Deg F, but can be set to whatever temperature the customer wants
