do you have a pic of the manifold you bolted to the heads over the intake ports?
Where is the ISV plumbed now?
Where is the EGR plumbed now?
Same with evaporative purge valve?
How did you get the rectangular throttle body adapted to the "round" IM inlet?

i chopped the stock IM runners and welded 1 1/2'' ID 40gauge Aluminum tube to the runners at the degrees needed to mate with the plenum and the silicon hoses help alot with the angles

how did you adopt the 12V oval body/rectangular base twin bore throttle body to the new IM that was machined to accept a round, single bore? And how does your throttle cable in pic pull the butterfly plate pully 180 degrees clockwise to WOT from the position it's in in that picture? Got pictures of ANYTHING besides just the assembled conversion?
Oops, nevermind about the throttle cable question. You would've just run it to the pully connection on opposite side of the one that came OEM so you could pull it open from the opposite side.

No offense intended, but perhaps a more permanent solution should be sought out. I can only imagine how short a time span it would take for your engine bay to go up in smoke if one of those injectors starts leaking.
A++ for effort and innovation, curious to see what that has done for power.

ISV - i used the fitting on the side of the TB normally used for
the EVAP as the ISV pickup and a fitting on the bottom of
the plenum as the outlet.
EVAP - re-routed the the front of the plenum
TB - i eliminated the plate on the plenum where the stock S4 TB
goes and that leaves a perfect space for the 12v TB. Tapped
the new threads.
sorry for the pic camera didn't focus the weld
