So I'm considering get a power programmer for my 2003 f150 5.4 and I'm looking at the edge evolution cts "gryphon" from power hungry performance. I have zero experience with programmers or chips or tuners or anything like that I just want something to give my truck just a little more get up and go but I do not in any way wanna sacrifice my trucks reliability. I want something easy to use and of good quality. Are there any negatives to the cts and will I be sacrificing any reliability in my truck? Motor transmission rear end or anything? Also I have my rear two cat converters cut off will this programmer allow me to keep my "ses" light off?
