Yea, I did it about 3 weeks ago, and it doesn't idle right. It idles kinda high until it has been running for a while. I bypassed the IACV and the TB. You can tell alot on those cooler night how much the difference makes. I am about to go turbo in a month or so, and when U change to the JG intake manifold, I am going to change out my IACV too.
