All I did was lower the pulley size and have it retuned and now I'm sitting at 562. which is exactly where I wanted to be. All with out any fuel or meth. Anymore I would be flirting with the edge of running out of fuel. I'm not sure what your goal exactly is, but if your looking for reliability on the basics. Then what you currently have/looking into is just fine. (meaning no adding fuel or cracking the motor open.

Are you running the zl1 tank pump? I have almost exactly the same setup as you and Ted j recommended against even getting into boost or starting the tuning process until I swap the pump. I dropped the tank a few days ago, Lord, what a pita for a 58 yr old working off of Jack stands! I'm going to attempt to get it back to together tonight but suspect it may be a two evening project. Your final results sound promising, can't wait to get mine dialed in.
