First off I did a search and like usual I got countless threads without answering my exact question. So, I want to know what would be the best size throttle body to use on my 07 Hemi with a sidewinder and supporting mods. I run a SC tuner so I don't have custom tunning ability. Will a ported tb make me run lean, will it even make a difference, is it worth the money? My truck is a tow rig and my DD, but I also like to take it to the track and flog it around town some. I am looking for a few little things to get the most out of the truck without messing with the towing reliability, or spending a fortune. Thanks for any info.
