Unfortunately you cant use the drive by wire tb . You will have to get an aftermarket one to use cable . Holley makes a 95mm that may work for you ,and there are a few more that do also .

I do think the tbss intake looks better than the truck intake .

Just another way to look at it . If you change intakes you are probably looking at best a 10 to 15 rwhp with your set up if even that with a tbss intake and bigger T/b .

Thanks for the help. I may go with these items below.
