performance mods for 5.4
All the programmers are pretty much the same when it comes to the mechanics of installing the tune. The person who writes the tune is the important factor. I have custom tunes written for my truck because of the modifications done to it. I use an SCT Xcal2, http://www.sctflash.com/ , with three tunes; 91 tow, 91 performance and 94 performance. The tunes are written by Mike Troyer of Troyer Performance. http://www.troyerperformance.com/cgi...&link=mainpage
I cannot speak to the competence of other tuners as I see no need to use them.
