OK..I was one of the members that got it free from Tbyrne

First off I put it on a 5.3 Yukon...as I was puting it on I noticed a crack in the UPD intake tube so I put the stock intake back on...til I got a new INtake tube from UPD.

I have checked MPG for 2 months now,,so Its time to post

I am very happy with this product..I dont know if it helped power or not im looking for better MPGs

stock = 13.7 MPG
UPD=14.6 MPG
stock intake and velocitystack=15.4 MPG
UPD & velocity stack=16.3 MPG

I thought it would be a big joke..but I was wrong...

just thought I would share with you guys what I think of Velocity Stack

 

cool. might have to try one of them things

 

I also have seen a increase in mileage and a small increase in power. The product is pretty cheap for the help it gives you. It pays for itself the first time you fill up

 

What is a velocity stack? And do you have any pictures of it?

 

Yeah and how did you get it free?

 

Are they for sale yet?? How much?? Do any of you who tried it out have a tb spacer also??

 

Looked on TByrne - can't find it in the truck section?? Always looking for ways to increase fuel economy.

 

i heard it wouldnt fit with the volant. Anyone know for sure?

 

On TByrne it's under "induction". I'm gonna get me one too.

They cost about $50, and as they first came out they had a promotion where I think they gave 5 away for free to get some people to try them.
