VR Velocity stack at T Byrne Motorsports
Has anyone put one of these on there ls1? They claim 13rwh on a ls1. For $50 this seems like an awesome buy. What do you guys think? Go to T Byrne Motorsports and check it out. It goes in the throttle body and help air flow.

Mine has been working great for me! The up to 13hp number would be seen low in the RPM range. Peak gains would only be about 2-3hp. It's not just the horsepower, it's the gas mileage improvement.
Something that was just posted in the Truck section of this site -
I have my 03 2500 hd. 6.0l
I was avrige 9.6 mpg.
I did the VR stack and a mac cold air and between my 80 miles last night and my 130 today my av mpg went to almost 11.
This was a mix of city and highway.
>>
I know this is with 2 mods together. Some people have seen just over a 1 MPG gain with the stack alone. I've been getting a .75-.85 improvement in my HD. Even removed it for 2 tanks and saw the mileage go down.
It won't help you get a few car lengths on your buddy but it has been doing something...
