I'm in the process of installing a Vortech supercharger on my 4.6 2v and trying to figure out lambdas I need to be running. For cruising with low boost (2-3 lb) would 1.0 lambda be sufficient and .8 for 10lb wot?

I also don't have the ability to change base fuel. Would forcing it to stay in cold loop be fine? With the cold loop, I have a load-by-temp axis but unsure if that will cause issues leaving it in cold loop.
