A little update for mine...
Here is a small test run clip. The car we are messing with in the video is my buddys 5.0 mustang. Its got exhaust, intake, programmer, gears, and under drive pulleys. My intent was not to race him, but he followed me on the first test run.
The first test run was me on 12psi and in a good rpm range. Actually seeing what it would do.So, we head back to the house so I could change a couple things. The next run was me on 8psi (untill the end lol) and way out of rpm range. I wanted to give him the jump. Anyway, towards the end of the run, you may notice the car start to sound different. I blew a line off the intake and lost pressure in my vac block, so no signal to the map or fpr. And at the same time had wastegate issues, which took it to 28psi.

The end result was a 14 to 1 a/f and egt's that pinned my zeitronix at 2200 deg. I am thankful I didnt hurt anything. Comp test is fine, plugs look fine, no noises. I think its a testament to how strong the Venoilas are.
Sorry you cant really see much as its dark, but I think its visible enough.
