Is it better to pull timing or add fuel when towing? I I'm thinking towing in first gear is going to be pretty light throttle once up to speed so it'll be running stoich. Should I just add some digits to the bdl table?

if its pinging then its got too much timing for that condition.

Yank the timing down at that rpm and map.
