external wastgate springs

[Sheldon]

what spring did you use if you want 1 bar boost?

if you used a 1 bar spring, did it hold 1 bar perfectly?

and if you used a 10psi spring and a boost controller to up the boost.. did it hold the higher boost perfect?

thanks

if you have a 1 bar spring then it will drop 1 psi or so or more when the rpm is to high for the tubby !!!!
