Leroy Turbo spool stick, made from aluminium and stainless.

 

Control turbo boost pressures, Just assemble the parts so it looks like the picture.

Note that GM-4 Spool Sticks will not require the lever that attaches to the turbo like the picture.

Instead you just clip the turbo end to the turbo waste gate arm directly 

 

Note: this will not fit a Chinese turbo unless you drill a new hole in the bracket.

 

You must run an in cab pressure gauge to be able to set the spring tension and monitor boost in the future.

To set the boost psi you just need to drive the vehicle as hard as you think you would ever need to then set the spring tension so boost psi is were you need it.

This will take several times adjusting the spring. I recommend 8psi or less on a stock tune and the ECM most likely will go into limp mode if it sees an over boost condition and some trucks will just go into limp mode if the vacuum system is removed.

You can set higher levels of boost if you have a ECM tune.
