changing my speedo

i am working on learning how to tune my 98 s10 before i mess with the ss so i don't screw it up.. any way i want to raise the spedlimiter, what is the speedlimiter2 about?? i moved the limit to 150 and the resume to 110, but the truck only gets to the origional 94 and stays, it still has motor but something is holding it, either timing, a limiter, fuel,, i dunno what else would need to be changed?

speed limiter 2 is usually for reverse.

change both limiters, make sure you also kill the fuel cut @ 94 too. that sudden cut hurts you.

my fuel cuts are set by rpms and not mph, i have the limiter at 150,resume at 140 and the speedlimiter is at 5600rpm way above where it still seems to be cutting out?
