personally I think jason will bust a much better time with the urd kit.. he has been to the track and he is very comfortable at the drag strip.. his truck is a monster.. I think you will see he will have some good times..
Also even though I dont want to admit defeat.. I think if we ever go to the track together youll find jason with a better times.. I think the urd kit will perform better on the track with the lesser tq bottom end will allow for hook up and the trd unit you have to feather..
Dont get me wronge I will run that young man for all thats its worth but I think then urd set up is the way to go.. Now on the street, I have paired up with justin when we had about the same mods.. we found that trd sprinted at first but the urd kit had more on the high end..
Honestly if I had to do it all over agian I'd go with urd.. its way more tune about for performance.. pulleys, intakes, blower sizes, ect.. Ive seen both and that my 2 cents..
