i just picked up a z6 head and im going to polish it and smooth down the exhaust ports, im also getting an aftermarket cam and intake mani, what should i use to tune it? i know i can tune the cam with a cam gear but should i chip a p28? or can i just use a vafc?

 

PGMFI.ORG chip it ...

hondata s200 sounds good to me. Are you going to supercharge or turbo it later? If so, I'd run s200 w/boost option.
