Flex Fuel Desired Boost Issue

So I've been getting my car setup on flex fuel and have noticed an issue with the desired boost not matching the actual boost, causing closed loop wastegate control to lock the boost at wastegate spring pressure.

I've fiddled with it a bit and have found that around 2x desired boost (desired boost at 32psi desired boost, the datalogged boost error will reach 0psi at around 16psi boost pressure (~31psi MAP))

I'm not too sure whats going on here, maybe with the e85 tables its trying to reach the specific MAP pressure where as on 98 its trying to use the relative boost pressure?

Thanks!
