Installed the JB yesterday. Disconnected the battery last night. First thing after opening the doors. Connect the battery bush it outside and start it up. I let it run at idle 20 min. Then took her out to see if there was a difference.
hyea: Holly Cow. Low end response.
To the 10's :2thumbs::clap: Like day and night.:thumbup: Put about 50 miles purred like a kitten. Not even a little pop when backing down. I'm at 1 foot. above sea level. Might have to disconnect / connect the battery when I get into the mountains.
