Surprise surprise I'm having problems with my eboost.
With the Sn at 0 I get around 9.5 psi. At 20 I get 10.5. At 40 I get 11.5.
When I turned it up to 50 boost went up to 13 and the engine started cutting in and out. There's no obvious abnormality on the log. Is .032" gap on the BR7EF plugs the likely culprit?
Also, it doesn't seem I'm gaining much boost with the eboost at all. From Sn of 0 to 50 I only gained 3 psi. And I have it setup with the 2 port method for "maximum boost your setup can produce." I'm starting to wonder how much boost this 475/83 1.0 T4 will actually make on this setup.

It's the spring that comes with the JGS 50mm....makes 7 psi on spring with manifold reference.
Also, Stock48 is running the same turbo (except 1.25 a/r versus my 1.0 a/r on turbine housing) and he says it just starts pumping hot air past 16 psi. I'm wondering if I'll start seeing larger boost gains from the 50-100 Sn range. I haven't figured out yet if the settings yield linear increases in boost.
Also, I'm going to pull the plugs and close the gap down when I get a chance.

According to the manual you should leave Sn at 20 or close to it. Adjust SP to get the desired boost then play with GP and Sn. I left Sn at 20 and it's been working great, but I'm using the 1-port method which gives me 4psi at SP=0 and 10.8psi at SP=55 (haven't gone higher yet) with the light JGS 50mm spring.
