Can't figure out why some pics show fine here and some won't. Unfortunately Trevor's pics don't show up. Appreciate the link though.

Trevor, I like the air filter mounted like that, where did you run the tuna can hose too?

Guess I should have asked, I haven't really found an answer, but once I put a manual boost controller on the waste gate, how do I go about setting the boost. I know mechanically how to set it, but at what PSI do I set it. What other info do I need to know about etc. Consider my engine is pretty much stock with a few mods. See Sig.

Dwayne,

Here is a picture of my home made TM. I need to tweak it a little more to make the spring set a little better.

I have a boost gauge and have the max boost set to 11psi at WOT.

put a peice of 3/4 or 1" copper over the spring along with a fender washer on the bottom it will straighten it right out thats what i did on my 99 burban and it worked great home made is the way to go

I have some pics on the site somewhere of the wastegate tied shut with a clevis and bolt, nothings going through there (25 psi boost), i wouldn't advise it though unless you have lotsa cash to buy a new engine when you blow it up!

I got mine from Sears. Try to get a few different one's to play with until you find the one that works best IIRC I got 3 or 4 different one's for about $2.50.

Same here. I got mine at the local hardware store. I ended up using the stiffest spring in the pack (I got the "spring assortment pack"). Then you set your max boost by tightening the nut. Wing nuts are good because you can quickly adjust boost. IMO there's no need to be able to adjust boost from inside the cab.
