Anyone know if we have a speed limiter on our trucks??

I've had it up on the ~125 range so far. I will be running my truck in the Big Bend Open Road Race for a few years while the racecar is being built. 125 MPH average (125 being the target average, not allowed to exceed 140) is as fast as I can go without installing a rollbar/rollcage and is the class I currently run my Mazdaspeed3 in. I know new tires are in order, the stock Pirelli's are not approved for that kind of sustained speed.

Obviously to get a 125 MPH average I'll have to exceed that for periods of time at the beginning and after corners that require me to slow down.

Your truck has been tuned then limiter is 100 MPH or 160 KMH

Yes, for 09-10 I know it's 96 mph.

You will need a programmer to remove the limiter.

I thouught your tuner eliminated the limiter, or at least let you change the limit.

RES4CUE

It does, I don't think he has one unless I read it wrong.

Updated original post, yes I have an MPT tune installed. Since I've had it to 125 I think it's safe to say that the limiter may have been removed... Hell, I don't remember what boxes I checked on the order form or when I installed it.... ;-)

I figured you were just getting numbers wrong but if it's 125mph then it's off. You should be able to hook it up and see if it's higher or on at all.

I believe pcm limits are 412 km/hr on these according to HP tuners. Not that it really matters lol.

Not that I'll ever do it but I turned my limiter off with my sctx4, I don't like being limited on anything.

my truck these days is limited by the number of demerits left on my license
