New system cutting out under load

[fintech]

I'm pretty new to megasquirt, installed one other system but did not have any problems. I have an EMS-PRO ms1. I'm using a Holley (GM Clone) tbi throttle body with two 85# injectors, ford 351W, MTX-L O2. Under light load it runs fine. When the system is under load its starts to miss, goes lean. I'm not sure if it tach related, injector, TPS or what. I'm still new to this. I'm running fuel only and the tach signal is coming from an MSD 6A. I have it set to Hall/Opto 12V pullup. I uploaded my logs and magasquirt file. I've tried changing the injector settings with now change. I've tried to use setting from people that are similar to mine. Any help would be greatly appreciated. I'm trying to figure out how to read and understand the logs.

Here is a video of my conversion. This might help people understand what I doing
