you'll be alright on high compression for around 200bhp, getting a 1.6 cvh to that on a non turbo engine only takes around 13psi of boost, my 1.8zvh takes 11psi to get to the same figure but more boost and less compression ratio (can't remember exactly).
use the thickest head gasket you can though. i reckon you'll get to 200bhp off less than 10psi of boost on a high comp 1.8 zetec.
why have three maps? you only need one as the map sensor should sort out fuel at varying boost levels.
