I was wondering how to go about removing the 96 mph speed limiter ...
I want to go the safest and cheapest route possible.
thanks in advance for any info!:)

I think you'll have to buy some sort of power programer, and make sure it has the speed limited raise feature.

You need a hand held programmer. Predator is what I have. Most cost about $300+ but you can find used ones.

Edge just fakes out your factory computer to do it's magic...a handheld programmer actually re-writes the program on the computer; and can change your top speed limiter (max usually 120mph), read codes, adjust speedo for tire size change, etc....

:exactly:

The 120mph max is about where you run out of RPM, stock tires might be somewhere around 115-117mph.

The hand held tuners do NOT remove the speed limiter...they raise it to 177 km/hr which equals about 118...

Ive picked apart PPE and Predator tunes and they are all set to shut fuel down at 177 km/hr. If you want to go faster, you'll need to:

A) raise the RPM limiter. Mine is set at 3,800
B) use EFILive to write a custom tune that allows fuel above 177 km/hr.

Please do this with EXTREME caution tho. The tires are NOT rated for this kind of speed and do remember you are in a 7,000 pound truck.

A tuner willl get you to about 110mph with the LLY. EFI Live or a custom tune will get you beyond this point.

Not to hijack but is EfiLive for sale yet or is it still the people who they chose to test it from a couple months back?

Wrong section, I know, but Ben, what tables are you changing to raise your speed limiter? I changed all that I could find that dealt with rpm and fueling at higher RPMs, and I can't get it to spin any faster...

B0747-Max fuel quantity vs. speed, set the "120mph" table to 120mm3:D
