I see validity in both. I see the need MAP for sudden changes in load without the TPS changing. EG, you hit a wave which slows the boat and RPM down but you didn't change the throttle or you bark the drives in a wave which changed load (MAP). TPS is pretty straight forward I feel. I have blanking in the 6 range for TPS and 7 for MAP.
Your deceleration enleanment issue is probably in your main table it I had to guess and it happens to quickly for auto tune to correct it and it might need to be smoothed. OR, you might need to turn the deceleration enleanment off all together. Something you have to figure out what's the right strategy for your tune.
It kinda sounds like the tune is a little jacked up to be honest if it's doing all that. In the end I have no way of knowing what's really going on with your engines without seeing it realtime and analyzing your tune. Not something I'd be willing to speculate on online or from a far.

Pissing me off .
Hard to try and figure it out on my own, be nice to have someone on the laptop while I drive the boat ... data logs aren`t giving me a clue why the main table calls for a certain amount of fuel but it swings like crazy on decel.
I need a day just to tune, hard to do when everyone wants to go boating but over everything else is fine.
Cold starts , idle, shifting .. all good now .. just a little more tuning and she`ll be good to go imop

Very cool, Dan. Been about a decade since we were up in Door County (stayed in Ephraim) and hit all the local spots including Sister Bay. It is beautiful up there. Had to look up that island and that is cool that you can stay on it.

Still having issues with this, can`t seem to figure it out .. if I throttle the engine will go lean and bog when I come off plane it`ll go 10afrs and then swing to 16-20 and sometimes the starboard will die.

I finally had a day just do only tunning and prop testing and got a lot accomplished and fixed
.The issues were in the main table not in the any accelaration Enrichment.
I cleaned a lot of it up .
Tried some new props and got real close to my number thou.
