According to Vortech (I called them) it will not work on the 03 GM's with a returnless fuel system and one is not needed at all... I wish iunderstood tuning these things better. LoL

i went out and looked and i do have a return style fuel system, not sure why the guy at Vortech thought I had a Returnless... So, if the factory one is built into the rail would it best to install some new billet fuel rails and then go with something like the Vortech FMU? Maybe someone has pictures of one installed?
Tweeder, when you say ratio do you mean Fuel Ratio of 10:1?
P.S. Sorry for all the questions, just trying to learn this stuff so i can make some what of an informed choice on my new toys... 8-)~
