so driving for barefoot, there is a slight change of experience problems with roller cam and original EFI computer? Ok, nothing should be out of normal range, except the cam (the not original roller cam was included in your reasoning). Also cooler air temp. in Finland, but this EFI does not straigth take that into account?
Or, as you said rich enough; If we know the max. output of the original EFI, we could calculate what is the base GM engine's max. requirement?
Or are these specifications publicly available? Something should exist at least.
