Detroit 60series DDEC III weirdest breaking up/misfire/smoke?!?!

This motor has had me scratching my head. Let me start with this...
NEW:
TRS/SRS
INJECTORS w/ORINGS
BOOST PRESURE SENSOR
FUEL CHECK VALVE AT HEAD
FUEL FILTERS
AIR FILTERS
FRESH FUEL/CLEAN TANKS

This motor only breaks up, misfires, smokes ONLY when ambient temperature is above 50 degrees farenhite. Only breaks up between 13-1600 when I put my foot gradually back on the throttle after dragging or coasting a gear down or accelerating after a down hill. It clears up if I mash it and make it build boost.. Runs perfect in the cold. I don't get it. Sometimes I do feel as if it derates it self. I bought a new pedal sensor. I need to install it though. (My DDECIII is a donor ECU it's set a 430hp and my injector numbers were updated to the ECU. ANY IDEAS ANYONE?! I'm sooo fried with this.

 

The ECU is 100% not the program my truck had before I changed my motor and I will be getting it reprogrammed. I just wonder if it could be valve adjustment. Like they are too tight? I have to check with the overlap phase once it gets warmer around here. I know my injector heights are at 80mm which is fine. It just drives me nuts. When it's cold out runs great all day. When it's warm out runs like ####.

 

I will check for good power and ground at battery box. Thanks guys

 

I think my valve train is mal adjusted... I just noticed even full steam ahead in 10th gear at 1600-1700 rpm at 70mph. I can hear it in the exhaust the motor not smooth, like chopping up.. And when it's doing this, I can smell raw exhaust. Maybe intake valve isn't closing all the way or visversa

 

Hmm, idk... I've never really check fuel pressure. Id have to remove the fuel temp sensor and hook up a gauge and see what it reads.. Anyone know what it should read at idle and what it should read under power?
