VR Tuned ECU Flash Tune Jeep Wrangler Rubicon 392 470hp 2021+

Its time to get more power out of your Jeep Wrangler 392 - 6.4-liter V8 engine makes 470 horsepower and 470 lb.-ft. of torque for the 392 cubic engine.

VR Tuned's new ECU tuning solution can help bring out further performance your car craves for. Gain up to 30 horsepower and 40+FT/LBs of torque with our ECU Flash. What is important is how the vehicles drives on the street and the power throughout the entire RPM range. Along with improved performance numbers comes better throttle response, faster 0-60mph time, and a stronger top end pull on the highway. The automatic 8 speed transmission has the shifting cleaned up while the rev limiter on can be raised to give you faster quarter mile times. This is the optimal tune for 93 octane vehicles. 91 octane cars can expect similar performance but with slightly reduced figures. All ECU tuning is done using the HP Tuners MPVI2+ OBDII system.

With a ton of extra features, this is the best way to tune your Jeep Wrangler Rubicon 392!
