lots of options out there, you can buy a canned tune online, from a shop, blackbear and others
prices vary, blackbear does tuning and improves the overall performance plud you can have the governor removed but it comes at a cost
cheaper alternatives include hypertech, and others

Its not really a limiter per say. The deal is that there are no more instructions in the PCM for spark, fuel trims, etc. above a certain speed. For instance, why would you want a stock tahoe to be able to go 150mph (Not on a drag strip)? Thats just begging to die going that fast in a vehicle that is not designed to be a race car and WILL NOT handle like one. There are no instructions for a K Chassis (Pickup or SUV) in the PCM that will allow 1xx MPH. They had to stop somewhere in the programming.
There is NO governor in a 4L60E tranny either. It will go as fast as the amount of engine you put in front of it until the tranny gets more than its rated for or can handle and grenades.
