QA1 K and Gen III

Yes I did, I have done two or three of these with the Gold Box. Only issues I have are:
1. Usually the MAP is backwards and will not let the car idle - simple as swapping wires
2. No support for transmissions
3. Have to use a drive by cable set up. They sell an adapter for LS type throttle bodies, them bought the matching size E-bay TB, about a $120 expense for everything, but works nicely

I am using the Holley Terminator X on an LS car I have built and see they have support for DBW and such. They have now come out with a system for Gen III's, and I would think of going that route if I did another one.
