Yes it does. It is definately worth the $30 or so they want for it. You will be going from 18-22 psi to about 30 psi of boost.

Yea i have a question to go along with that. Is it safe to use it with no boost gauge? Whats the max psi for the stock turbo? I would like to use it but i dont want to blow up my turbo.

it's a good idea to have a mechanical boost guage when messing with your boost. i wouldn't go over 30-31 psi. i'm running a boost adjustment set-up from kennedydiesel and its really nice to play with, but i also have more than enough fuel from my programming to make 30+psi.

how big of a tuner? and i think guages are always a good idea when putting something like the boost valve on.

gauges are a good idea no matter what you do.the boost increase valve will help in turbo response and more boost,now they say the stock turbo will not hold up with 35psi for long but on my LLY i have been spikin 40psi and hold 38psi on a hard throttle for the last 20k miles to see how long it will last(i wouldn't recommend doing this if you want long turbo life)but i have never had any problems out of the turbo doing just this with it,knock on wood.i would stay within the 32psi as recommend by the aftermarket guys..

im going to either throw a diablo or a ppe on it and just a boost valve is there some type of a adjustment so i can kept it shooting under 32 psi and im not going to do much more but what type of gauge are you recommending with this set up i guess i dont understand why you would need a gauge if the boost increase valve only increase it to around 30 ?

You would want to have the boost guage to make sure the boost increase valve wasn't messed up and giving you too much boost.
