[QUOTE="Chris, post: 433698, member: 1"] 3000 RPMs isn't going to hurt a thing. You could run it at 6000 RPMs and it wouldn't hurt a thing. The rev limiter is there for a reason, to prevent you from blowing up the engine. The [URL='http://jscan.net']J-Scan app[/URL] will allow you to recalibrate the speedometer from your smart phone very, very easily. I would do this before anything else. You'll need one of these along with the J-Scan app to connect to your OBDII port from your phone: [URL]https://www.amazon.com/gp/product/B06XGB4873/?tag=jkforum-20[/URL] [/QUOTE]
