i was wonder what ways of adjust boost are out there. i have(currently) stock 00 with a manual trans and i know the engine could use a few more psi. other than just letting the turbo spool up to its max(pinching off wastegate like) how do you adjust boost? do you adjust the wastegate arm or something? thanks guys

You need an adjustable boost elbow like this:

One of these will also work wonders for you:

Turbo Master TM-24.

"The model -24 is designed for the '98.5 - '02 24 valve trucks with manual transmission. It is a direct, bolt-on replacement for the factory boost canister on these engines. Installation involves removing and reinstalling the turbocharger and typically takes 1-2 hours using basic hand tools. No special talents are required. All necessary parts and gaskets are included in the kit. A preliminary boost setting procedure is detailed in the instructions. The -24 range of boost pressure adjustment is 14 - 39 psi. This means that the -24 can be used with an otherwise factory stock engine without setting ECU codes. Simply follow the recommendation for setting the boost limit at 20 psi."

They are easy to install, and easy to adjust for different situations.

My adjustable boost elbow does not do anything for me. I get 30 psi with it open all the way or closed all the way. Any ideas why? It it normal with my mods?

Would there be a possibility of over-speeding the turbo causing a slobber-down-come-apart?

Check for boost leaks.

Above 35 psi, I think, the stock HX-35 becomes inefficient, so there is no gain in running more boost than that. And yes, if you overspeed or overboost the turbo it will not live long.

I tightened up all of my IC piping clamps this afternoon. I'll let you know what happens.

No dice. Still 30 psi max is all she will put out
