Sorry don't want to be a party pooper but the M44 is not low compression it is 10:1 and can not handle a lot of boost without a chemical intercooler/octane raiser or race fuel. My opinion is 10psi is the max boost without race fuel or meth injection. You are 100% correct that low intake charge temps lower the detonation/ping of the engine.
Intercooling and you might be able to squeeze 15psi out of it with a good tune
