Any feedback on Red Bullet Modified VVT-i Solenoids?

Does anyone have any feedback on the Red Bullet Modified VVT-i Solenoids? I see that people like them. There's one dyno that shows about a 2hp increase, but it also sounds like there's a mpg gain. Also, if you have them, were they difficult to install?

 

You can probably find more info in the group buy threads, or maybe @SUMOTNK can give some info.

I provided OP (via PM) as much knowledge that I have about modified vvti solenoids. That public info is laid out in the 2nd GB post.

 

Dyno chart of before/after on my personal truck. Its not about peak HP gain @Revelations The delta between the two curves is what is significant.
