I have a turbo setup on my truck I have an external wastegate. on one port of the wastegate it builds 8 psi on the other port it builds 20 + psi. so I bought a manual boost controller tonight It does not have a diagram and I have tried hooking it up a couple diff. ways and still don't build more than 11 psi. I am shooting for about 16 psi. And yes before I am asked the motor is a 5.3 with a forged rotating assy. any diagrams available? I have searched and all the diagrams I have found contradict one another.

 

On my STS kit it came with a "Boost Controller". I never could get it to work no matter what i tried.. So heres my new one i just built. Theres 2 pictured cause everything came in Pairs..

 

send one to me...

 

Those work good

 

you need to get a vacume signal from the intake manifold going to one side of the boost controller and then hook the other to the bottom port on the waste gate and leave the top one open. Then turn the dial till you hit your desired boost level. It should have an arrow showing which direction to go on the boost controller unless it looks like the one from above, which I really like by the way!

 

You guys can PM me if your interested in these MBCs..they are cheaper than dirt to build.. when i get through testing mine ill show a price.. Got to make sure it works good.
