So....im about to buy the HO cams and intake, but after researching, i think it would be best to buy a programmer first. What is the best programmer for the 4.7?? I've done alot of reading on the matter, and am finding alot of mixed reviews. What works for one person, doens't work for the next. Any thoughts or ideas on what works best for the 4.7? I have a 5 speed also....(not sure if this matters.)
