i just got back from some street testing with the low boost actuator set to very little preload (2mm). so the wastegate pressure is ~5psi, and it creeps up to about 15psi and stabilizes.
i used the haltech boost control to set the boost straight to 15, but i had to run 100% wastegate duty, so i'm going to replace the low boost canister with the original medium boost canister and preload it to run 15 psi and do some fine tuning with the boost control solenoid.
the turbo response is great. had 15psi by ~3300rpms, and this turbo is physically bigger (comp wheel, turbine wheel, and turbine A/R) than the previous Precision 6262 setup and has better response.
i am not happy that i can't run less than 15psi. i am going to see if i can do anything about it.
