open up the exhaust and intake and turn up the fule. make sure you have a pyro first. and dont go much over 12 psi unless you like replacing head gaskets or install head studs. depending on the design of the turbo the housing may be the main exaust restiction. keep in mind that load=boost so you'll get more boost towing or driving up a hill.

Thats just the nauture of the beast, I'm afraid. I saw 15 psi with my 6.9 once, but there was a lot of smoke to go with that. But if you want to have it both ways, just drive with a lifgter foot when you want better economy. If you have cruise control, adjust it for less max throttle. Allowing the RPM to go higher before upshifting will also help you get more boost.

I saw the pictures on your other thread:

But never heard of them before that. What are you getting now, and have you turned up the fuel since installing it?

Wait a minute, you didn't turn up the fuel? If so, that IS your problem. When I first installed my setup, I drove if for a little while without changing the fuel setting, and only saw 5 psi (squeezing the carpet down under the go pedal), and barely any change in power. Bump it up by one to two flats of the allen wrench and enjoy

Do you have gauges in there yet? If not you should get some before having too much fun.

Techno Babble: The amount of boost a turbo can make depends on the amount of exhaust gasses that flow though the turbine. And since more fuel burned produces more exhaust gasses, more fuel gets you more boost. (more fuel = more exhaust gasses = more boost = 'mo power) there is of course a limit to how far you can go with fueling, but you are clearly not there yet.

gasgrunt88,
If you see black smoke under acceleration you will gain nothing from injecting more fuel.
There is a limit to the amount of fuel you can burn because of the amount of oxygen in the cylinder.
Black smoke means you are over that limit.
Also exhaust gas temps can get high enough to do serious damage with more fuel.
Pistons can and do melt.
Best to not adjust fuel unless you have a pyrometer.
