If you the read website the kit is 2.9 liters unless its an error on the website

 

That's a error. They have a 2.9 but it's not available for the trucks to my knowledge. Although I imagine it could be adapted with some work.

 

It appears to be a completely different setup, as it is front-inlet and the only LS manifold is for the LS3 heads on a Camaro. If you're going to do that much footwork to install a twin-screw on your truck, you may as well go with Kenne Bell, as the support at that point will be about the same.

 

Ok I'm leaning towards the whipple why should I go with the tvs why the whipple

 

We've already covered this...

 

Read some of the above posts.

 

Yes I have over and over correct me if I'm wrong but tvs basically has more option for future upgrades than the whipple as far as performance they sound like they would do the same as long as they were setup the same way

 

Ya basically. In my opinion anyway.

 

Hey you guys that r running tvs2300 which kit did you use or is that a custom setup because all I see for trucks and suv get the tvs1900 is there a big diffrence in performance

 

There is no performance difference its just that the 2300 will support more boost on larger CI motors. It all depends on how much boost you want to run.
