VaraRam Velocity stack - who wants to try a free one?
I wonder if they will work with the Airaid intake tube? I'll go compare it to my stock intake and see if they are different.

There are alot of replies after my last one so this will be a general reply 
I run one of these in my '02 HD that has electric throttle control. I'm surprised that 2003Silvyrado had a problem because we're also sold alot to 2003-'04 owners. I'll have to take a look at the TB so check out that hole. I was courious to see how well this would work when it was released. I installed it after work and then went out that night. At one point I was sitting at a red light but not really paying attention. I looked up to see that the light had been green for awhile so I layed into it a little (maybe to about 3000-3500 RPMs). The truck felt better than it usual and then I thought "hey, it really does work!". I wouldn't say that it's like bolting on a set of headers but the throttle response and low end power picked up. That is what this mod is designed to do. It might only show a few horsepower gain in the upper RPMs so it won't help you get a few truck lengths on your friend. My gas mileage also increased by about .6-.7. I drive the same way in the same area so I pretty much know what kind of mileage I'll see. Others have posted higher gains in the past. The price for this is $49.99. Sorry, we can't give away/discount any others. Doesn't hurt to ask though
