tach is off....

Does it have any kind of aftermarket ignition?

your tach has to be off, because the rev limiter on those cars is 8200. Get a new more precise tach, and make sure it is JDM

Your stock tach is fucked.
Why would you want to rev past 8K anyway? Power band on a stock EM1 drops off after 7800.
Tell him to drive like a normal person.
