I have an LS3 cruise and connect kit from GM. In the wiring harness there's an RPM wire that connects to the RPM gauge. I have speedhut gauges, they supplied a 4.7 ohm resistor that gets wired to the RPM wire from the harness. Once connected as per speedhut instructions, the rpm's don't seem to climb as much as I would think it should. Idles at 500 but just seems sluggish. Has anyone experienced this and what did you do to fix it?



Thanks in advance
