2017 f150 whipple questions

[tjh566]

Hey guys, very new into tuning, I bought the coyote cookbook and have read through that which has shown me a lot of things. I've downloaded the whipple base tune and I'm looking at the wot lambda fuel table and they are specifying 0.82 which is high for a blower, but in reality, it runs very rich at 0.70-0.72 when wot, why is this? I haven't modified anything from the base tune yet, just looking around. Also, I'm switching to a smaller pulley and higher octane, what's the best way to go about adjusting the speed density tables to accomplish this? Is there a known ballpark value per psi to adjust by? Thanks.
