ASA layer adhesion issues

Wondering what folks would suggest for better inter-layer adhesion with ASA - I got out a long print that was looking successful in all ways except in some places where the layers separated. This might be ok for some prints, however this one is not only functional, but also is intended as an outdoor electronics enclosure.

On first attempts I was dealing with warping off the bed, but solved that with higher bed temp (110), turning down the fans, and preheating and taping off the build chamber, so that it maintained around 52 chamber temp the whole print and that solved build plate warping issues.

Besides bed temp and fan speeds, it's running on the default Generic ASA profile (this is Sunlu ASA, if it matters). I'm thinking the next thing I'll try is cranking up the nozzle temp - maybe 270 or 275? What else should I try?
