It's running 35 mph with a custom tune now that sport mode is unlocked. Had to sign a waiver to get that feature unlocked. Still haven't checked the range on a charge yet, but I've only charged it up one time since I did the conversion (was down to around 75% SOC), and this cart gets ridden daily, so "I think" the mileage is better. Hard to ride the thing 30 plus miles without leaving the farm and all of those steep hills.Just did an AC PM conversion with the Teekon Silver Wolf kit on the cart(similar to the Tesla motor technology)....hoping for even better efficiency (and Speed!). A quick run up showed 26 mph on the standard setting. Emailed the mfg for a code to unlock the Sport mode that is supposed to add more speed and torque.
