The ez for less than 2k does include the Tb and ignition, (xmi stand alone ) which is the same box as the full xfi hemi kit runs. Actually the xfi full system is self tuning now also. And the Ez includes the programmer to set the parameters to get it going , also includes a wide band O2 ,.I have read a lot on different forums , heard a lot of good reports with this setup.
Hey if you found all that stuff that cheap thats great, and I am not trying to one up you. I am just throwing this out as an option .
Some guys prefer to spend $800 -$1k for a custom carb and some prefer to buy a used carb and self tune it themselves for a little of nothing , same with EFI, everyone has ther idea what is the best deal I guess.
I also work on cars , I just flat out don't care for the tbw throttle bodies, I have had cars that were towed in as no starts , that ended up with problems with throttle bodies sticking etc. Just dont care to have one on my car personally.
