No such calamaties will occur in particular if you have FCR 41s which have more than adequate flow. Going to the 944 with 11:1s, my mains stayed at 155, slows acutually decreased to 55 from 60 and the only additional fueling I adding was a slightly richer taper on the needle to help around 4000 RPM. Probably had that stock anyway. I re-iterate, the only reason your 944 kit will exhibit pinging tendencies is the increased compression and not carburation, at least within a range close to stock settings for carbs & timing.
