i do want the car one though lol, one thing at a time! The car one is machined much better too

 

Since you are currently running the truck 87mm you can use a LS3 without altering the pink wires on your Xlink. LS2 requires them to be cut. Also the LS3 TB blade opens the same as the truck, the LS2 opens the opposite direction. Not sure if it really matters but just some more FYI. Also you can pick up a new LS3 pretty cheap on ebay at the moment. Thats where I got mine.

 

is that a returnless fuel system?

 

yes it is returnless
