my predetor will only lift the speed limiter to 125, i have built a custom silverado and it can slam that speedlimiter and stop in just a few seconds than im just sitting there, i would like to know how to lift it completely or the highest number possible for the drag strip, thanks

Than what about some kind of trade in deal as i was hoping to get a programmer soon but ultimatly want a trinity... can i buy a predetor now and do some kind of trade in or should i just wait till this unkown date for the trinity? you are saying that there will be trinity support for my truck soon ...

When will 2001 silverado 4.8 support be added ?
