We leaned it out and got it in line with yall's AFR recommendations. However, it didn't increase the peak boost.
I was looking at
BNR's page and noticed that the Stage1 is supposed to come with an adjustable wastegate actuator pre-adjusted to 7-8 psi. And if you'll recall, with the EVC turned off we were only seeing 4.5psi. Ah-ha! Bryan forgot to adjust the actuator. Single-man, busy business and shit happens. No biggy. So Friday morning I sent Bryan an email asking him if he had a procedure for adjusting the WG actuator.
I hadn't gotten a response from him by yesterday (Saturday) afternoon so I Googled it and found that on other cars they adjust it by shortening the rod until they just have to pull the rod to refit it to the lever; just a touch of preload. So I put the car up and crawled under it to adjust the rod and... no threaded actuator rod. So I sent him an update email.
Bryan responded shortly after midnight apologizing for installing the wrong wastegate actuator and said to "Add a spring to it and it will gain a couple psi." I responded one minute later asking what size and rate he recommended but alas he did not respond.
I found on a
Subi forum they recommend 4" 19.1 lb springs from HD. Any recommendations specific to the Hitachi? Can I put my MityVac on the WG nipple to test that it opens at 7-8 psi?
Thx
