Stalling with ms2

Stalling with ms2
So I'm running a basemap from reverent. It was made for 650cc injectors so we rescaled to my 775cc.
Car starts ok, though sometimes it cranks for a while (if it's been sitting a few days) and then starts. Sometimes it will fire up and be fine, other times it fires up, goes to 2000rpm, then rpm slowly drops and it stalls. If I try to keep it alive with the pedal it feels like it's firing weird.
When the car is driving around its fine. Good cruising, and I'm keeping out of boost until I'm tuned in a few weeks. However, once the engine gets warm and oil pressure drops down to its hot range, problems begin. I was on the highway for about 20 mins yesterday and it stalled at the next two lights I was at.
When I depress the clutch, rpm drops by about. 300-400, sometimes stalling the car. Other times just getting into neutral the rpm drops too quickly and the car stalls (even the slightest touch of gas pedal when rpm is dropping keeps the car from stalling). This all gets worse once my 14" spal fan starts coming on. In an around town situation where my fan is on, and I'm coming to a stop at a light, it's almost guaranteed to die. It's not a violent stall, just as if someone turned the key off. If I'm standing at a light with the fan off and it comes on, it will also stall the car (only when it's warmed up). However if I force the fan on with the ac button, rpm increases like it should. Once I turn the ac off, rpm fluctuates up and down for a few seconds and then settles down.
Someone suggested my injector dead time could be wrong (definitely is because FIC gives dead time at 12 and 14v but not 13.2). Any other ideas? I'm sure the tuner could work it out but I wouldn't mind fixing it myself since I still am breaking this motor in and just gently driving around to work and such.
Thanks!

Hot restarts are fine actually. Odd

I'm experiencing the same issues or similar
Cruising and coasting to a stop while out of gear
Cruising and coasting to a stop and downshift gears to a stop and it's out of gear for the last 10 felt or so
I sometimes can take it out of gear and it keeps the gears idle high enough to keep driving without using the acceleration pedal
Shuts off at a stop of the other symptoms do not effect the idle prior
I have several logs of each issue in all 3.-
I can send you the log

That log still only shows 1 sample every 1 or 2 seconds or so, when it should be 20-25 samples per second. Check that the TunerStudio program bar (top section of the window) says TunerStudio MS 2.0.8.
If that is the case, check Communications -> Data Rate. It should be set to at least 20 samples per second.
