It's kind of hard to tell how much without verticle line on it but why it looks like you're leaning out a decent amount between 1 and 9 psi. I guess at that point you're still only at a couple psi so it shouldn't be an issue, but still shouldn't it be decending steadily?
it's all the same. actually straight up dumping in fuel will spool a turbo faster.
Sorry for the thread jack but can you explain this a bit more? I thought I richer mixture burns cooler and a leaner mixture burns hotter. If heat is what's spooling the turbo how would a cooler mixture help that?
