They don't leak while driving since the fuel is being burned up, so I would do an oil change and then drive to the new house directly.

You should really let the logging tell you where your limits are. There are too many variables to say a blanket statement like you should be able to run 20PSI with X turbo. Start at map 1 and then...

You could also check if there is gas on a plug after sitting for a bit. That would indicate a failed injector as well.

I am no pro at all, but is the slight jumping around of ign 1 vs everything else indicative of a spark plug gap or injector/coil issue on cylinder 1?

PS. I pretty much stalk your build and now...

All of this just sounds like misfires to me from the cylinder 6 injector. IIRC, you have to change an entire bank (1-3 or 4-6) at the same time. Did you re-code after changing the injector?

Does this manifold add more space around the OFHG? Can you remove the OFHG without removing the manifold?

Thanks all for the responses. I got busy and didn't get back to respond.
That new intake looks great! I might just go that way and start the single turbo plans.

Most people drill and tap the manifold and put a 1/4 inch NPT and thread in a copper nipple. The plastic nipple breaks all the time and people say doing this make the Tial BOV work better.
