Has anyone ever heard or used one of Street and Performance Electronics manifold spacer on a 5.7 vortec?

Street and Performance Electronics Vmax manifold spacer

from the dyno it says it is good for 22hp and about 26 lb of torque. Can anyone verify this? Does it work? Any problems?

 

I have seen this, but i have heard of no one that has used it. Seeing that the inside of teh 96-2000 Vortec305/350 engine is VERY cluttered with teh FPR, injectors and fuel supply hoses actually in the air path, I would bet that you would see some gains, but I dont exactly know just how large they would be.

You wouldn't happen to be from Arkansas would you? I was going to have my truck dyno tuned there but I decided not to after I heard that they do some sorry tuning. I have also heard that they are way overpriced, so this may be something to consider.
