Had it out yesterday. We have 26° total in @2000 RPM and back down to 18° total @3500-16000. Pulls like crazy with the Lambda at about .83, going to try getting that down to about .75 Lambda. Keeping an eye on the Injector DC, we were only at about 70% yesterday at 5900 RPM.
Only about 10# of boost. Cracking the block not withstanding, how much timing can we put into this thing with E85 at 10PSI?
