I've had my 02' zx3 with the zetec motor (of course). My tach doesn't have a redline on it. It goes up to 7 G's like I'm sure you all know. What is the actual redline for this car? I would think if it couldn't go up to 7 they would put a redline on it, but I'm not sure and kinda scared to do it until I get an answer for sure. Also, if it makes any difference the only mods on my car are a custom catback exhaust, and I took the resonator off my air filter.
