If i have no rav limiter does that mean the car has been chiped or the computer modified? Because I have accidently taken my car to about 6700rpm, and I thought the rev limiter is 6200 or close to that.

factory tach???they are not to be trusted imo.just take off the passenger side kick panel and take a look.

not rev limiter...fuel cut off at 6250 and like stated already you cant trust hat tach, you could be alot lower. when you hit it youll know it

I always wondered the same thing because my '88 doesn't seem to have one either.
I know the factory tachs are not accurate but you would think the rev limiter would kick in at some point on the factory tach......right?

besides,that rpm is valve float material......trust me you'll know[sm=trust_me.gif]

What will an aftermarket chip look like...maybe I'll take the kick panel off and look.

Quik

pull of panel, grab ecu and look on back port. if you see a thing there its a chip, if the factory tape is there car has never had one[chip]

I didn't think my car had one either I've missed a shift and accidently hit about 7,200 rpm.No popping I've hit rev limiters before but mine did nothing.

same here, I missed a shifft and reve till the tach was at the end of the red about 7000, and the fuel didnt cut off. neither did a rev limiter.
