I have looked on this forum, but haven't found an answer. My 06 4X4 4.6l needs some power. I have an Airaid intake and a Flowmaster with dual outlets and I want to get an xcal2/3, but I am curious as to how much of a power increase I may get from adding the programmer. Great forum and I appreciate the help.

there is no way its only 7-10. i ran the canned tune on my 4.6 while waiting for my custom tunes to arrive. 7-10 is hardly noticable but the x3 canned tunes were a huge improvement over stock. but this of course was after i already did intake and exhaust
