Ok I'm sure this has been asked before but here goes. My 03 Fx4 cuts out at 140 km/h (87 mph) and my friends 03 Fx4 doesnt cut out at all and the trucks are Identical. The only thing I can think of is that his was built in Ontario and mine was built in Pennsylvania or some thing. is there a chip I can remove ? It's kinda a pain in the ***. My 95 ranger cut out too but went to 160 km/h.

 

You can buya superchip for like 300-400 which will not only remove the limiter BUT also make you significantly faster than him!

oh ya. Is that the programable one?

 

honistly Bama programer, removes speed limiter, helps shift pionts(auto), increases HP/TQ and gas millege

 

as far as ive taken mine... its never cut out. ive brought it all the way up to 105mph and it never even started to slow down.

 

5 years difference, and 2 different engines. Why is this relavent?

My truck was doing 115 MPH, before it hit the governer. I took it to the dealer after posting here, and had them reflash the ECM. Now my truck tops at 99 MPH.

Why exactly is having your truck top out at 87 a "pain in the ***"? Why do you need to go that fast anyway?

 

Cause it's not really cool when you go to pass a couple cars and and the friggen thing starts cuttin out.

 

Regardless, it's chip it, or reflash the PCM -- there's no other options that work.

 

haha sounds like u speed alot to be passing cars that fast and its not a speed limiter its a rev limiter, i had one on my automatic 2002 XLT 4.0 and it ahs the same on my 04 manual.. both stop at 92mph without any upgrades..

 

Ya I dont know if its a rev limiter cause I'm not over 5 grand on the tac when I'm doin 140
