I been using the Pred for about a month now. I love it, but I can't help but feel like there is more in my truck. JBA's are going on this week, but I was thinking of a new programmer. Can anyone offer a real world comparison between these two. I have an 04 SC 4.6L. If I were to buy the Troyer, will I be impressed?

 

I had a diablo custom tune, then changed to a TP custom tune, and without any other mods picked up over 25rwhp. Call him, you'll be impressed

 

I guess I am confused what a custom tune is? Isn't everything on the Diablo a custom? What work is required from TP? Do I not do all the modding? Do they send you the mods?
