Yes - I suspect a leaness - but not enough to cause hesitation/missing. Could be BOV - I had to make up new gaskets. Don't think you can buy them.
If the turbo 'lag' is the actual spooling up between ignition (3000) and lift off (3500) I have no complaints. It feels very progressive and strong. I have not yet really sensed the 3500 peak. From 3000 it just pulls like a JATO.
I have my idle AFR at around 11 trying to correct for this because at race temp under light throttle I'm at about 14 , and previously it was leaning out to 15-16. So, I suspect I'm still on the wrong end of the edge. Once I get that right, I will look at more early advance and see if I can't tweek more from it.
If the BOV doesn't seal well, what happens?
