The idle is near stock... Here is a clip of it at idle and with light throttle. As for the air assist, it works great. I had about 1500lbs in the back and it only took about 45 psi to level it back out. It rode pretty nice with the load as well.

 

How do you think that would work with a turbo set up? Wouldnt think it would be in boost all the time if the turbo is not spooling am I thinking correctly?

 

I have read a few posts over on ls1tech and it seems to be a good fit for most FI applications but I truly don't know how well suited it is to a turbo application.
