I just ordered the Kennedy boost stick off of the website. Can't beat more boost for $90! I was wondering how difficult it is to install. Is there instructions on how exactly to install it?

Very easy to install.
Might want to read this thread:

When I ordered my boost stick from kennedy, they only had it for the LLY. Members here said that it works fine with the LBZ though. Now I see that Kennedy has a boost stick for the LBZ. Is there a difference between the LLY and LBZ boost stick? If so, would I be better off with the boost stick for the LBZ?

From what I read, yes. You should go with the one that is specified for your LBZ.

X2!!

The only difference is the title. The Boost stick is a good way to give you the boost that should have been included in your tuning ;)

Thanks John!

i've orderd the booststick an took it off due to runnig the edge evo. i dont think these will work rite together. seem to make to much boost. any help on thiese sticks an a programmer at same. i think the evo adds boost also...sooo ??? thanks

Not as many programmers these days have increased boost. I supposse EVO does, so you probably shouldn't run the boost stick with it. Might blow up the turbo... I have a triple dog with the outlook, and I have the boost stick coming. The triple dog does not have added boost.

I have a PPE economy tuner on my LLY. Would the boost stick work alright with my truck? I am getting pretty good fuel mileage with this tuner, but there is a little lag. For $90 doesn't sound like a bad deal for a little more power.

Bought one and it works great on lower settings (up to 3) but not higher ones. I took it off and probably won't be putting it back on (I'm addicted to S/L). Super easy to install and again, works great @ stock and lower power.
