SD tune-- What numbers do you have in your secondary VE table at 1200 rpm idle.
Mine are in the mid 40' and I am still rich, what's wrong here.

Might be the injectors. My SVO's seem to run rich down low too. Think it has to do with the offset. Waiting on info from another member who claims to have cured it.

VE at low rpm on big cams is that low. i've seen it go down to low 30s, so it's nothing scary yet. keep going down. what kind of MAP do you get? How much timing does it get?

Right on Man. I dropped the VE to about 36 in the MAP 70 at 1200 and it idles like it never has, at 14.7 with the LTFT close to 0. I went for a run in the country and the wideband is stuck in the 14's. It's looking good with this SD tune. Things are finally working out. I'm going out for a track day next Friday, I will check back in on this post.
