Be careful. Lean is fast but too lean will cause detonation. Its tempting to go as lean as possible. I ran higher compression with a DC 30 cam and struggled with detonation as I tried to get everything out of it. Would log AFR every drive and make changes to try to get the cam matched to the MFI. That engine was a screamer, FAST!
