Firstly let me apologize if this has been covered, I did not see anything specific to the 4.6. I have a 2010 Scab and am mulling the idea of a programmer. First I must say there seems to be more for the 5.4 and the gains are higher. The gains on the 4.6 do not seem to be that significant in comparison. Has anyone installed one in a 2009 or 10 4.6 and what gains/improvements did you get.

Thanks in advance
