Hi All
Thanks in advance
I have a 97 formula i was racing a 5.slow mustang and had him beat untill we hit about 120 -130 and my acted like it was running out of gas. i guess it is governed at around 130...Anyone know for sure?...So my other questio is if i put in a chip or program it to have a top speed of lets say 150 do i risk damanging my engine? If so what is the best top speed and Rev limit that this car can handel? Thanks for everyones time and help

Doesn't sound like your problem is a limiter. If you got to atleast 120+, your limiter shouldn't kick in until 160-163mph. Also you can't get a chip for your car, you will need the PCM reprogrammed. www.pcmforless.com

Other than the non-Z rated tire speed limiter (your speedo wont read past 110 I guess), I never knew there was a limiter

Is there really a 160 limiter on OBD II cars?

My 94 is set for 255 MPH

Yes the OBD II cars are limited
