I have a 2016 Unlimited Rubicon with a Sprintex Supercharger, automatic transmission, 37's and a 3.5" lift. When I'm driving on the highway and I press a little more on the throttle, the Jeep seems to surge. This usually occurs around the 2.5-3k rpm range, right where the green ECO line on the tach stops. Also, when it's in this rpm range and it's surging, the ECO lights comes on and off with the surge. It's worse when I'm in 5th gear but it's done it in other gears as well. I can turn and set the cruise on and it will stop the surging. The Jeep is tuned with a Diabosport handheld tuner and the tire size have been calibrated. I have also used the AEV tire calibration tool that plugs into the OBDII that came with the lift.

Any thoughts on why it's surging? The Jeep runs fine other than this annoyance.

 

Get in touch with Jon at RPMExtreme. He has the low down on the tunes for Sprintex Superchargers.

 

Thank you. I will get in touch with him.
