Cooler Thermostat. Bin changes needed?

Would like to switch to a cooler thermostat in my 94 Chevy Pickup with a Vortec 350 and TBI mounted on it.
Currently running a modified BJYL.bin $0D mask.
And changes to the bin that need to be addressed, or recommendations on changes ?

Thanks

Might need some small tweaks but not much else. Just run it and datalog.

if you have ecm controlled electric fans you should tune them to come on a bit sooner, otherwise the thermostat will only show benefit during highway operation

you might be able to pick up a couple degrees of timing advance due to the lower operating temperature, but i'd do it in a spark vs temperature table instead of the main spark table (in case it gets hot again)
