4.0 shuts down
I recently bought a brand new ranger edge 4x4 king cab, I love everything
about it except it shuts down at 99 MPH! It's got the white racing gauge
clusters that show 120 MPH,can I get a chip or something to get all her power
without voiding the warrenty? I've got pics in gallery titled 75' highboy.

You need a chip to bypass the speed limiter, you can get more detailed info by posting in the Computer/Tuning Forum:

You will be voiding some of the warranty by changing chips. In general, things impacted by your mod will have the warranty voided.
BTW, you're not gonna try to make that needle point to 120 just because it's there are ya?

whoa,nelly
my 03 level 2 cuts out at 90.the truck could go 120 or more easy,but the tires would be past their speed rating and explode soon.that not pretty at speed.its a friendly lifesaving reminder from an engineer who thought of this. you could put on tires that could take it and write over the pcm or chip it.my tires are at 25% tread so this affects that mph some,may be 99 with new tires or model specific.there may be other reasons to not go too much faster with this rig. I don't wan't to find out the hard way.
