| Finally got my Z1 throttle bodies installed thanks to Rob at Z Car Garage. I was delayed since I had to send one back to Z1 to be adjusted since the butterfly flap wasn't closing smoothly and was sticking under force - scraping the wall. 
Apologies for the dirty pics - I really need to clean up and dress up my engine bay :) Anyway Rob did a couple dyno runs before and after at stock boost (10 psi) and the car made almost 20hp extra. I'd say that's worth the investment. You can see torque curve down really really jumped up though and I can really feel that. 
It made almost 370 rwhp at 13.5 psi. The car made almost 389hp@~14.5psi during dyno tune pull at Specialty Z before adding the TB's. Doesn't seem the gain's are exponential as the boost increases in fact it may not have added any more power on the high end at all.
He noted that with the stock linkage springs as-is the flaps didn't seem to completely seal and the car would idle rough and fluctuate or wander sometimes. He cut down the springs by .25" on each side which added some additional force to close the flaps all the way. Idles perfect now. Gas peddle is a little stiffer and pushes back quicker but I really like the way the response feels actually...
