I have started to tune my truck and I'm not getting the results that I was expecting, I'm pretty sure I'm missing something in the tuning and was wondering if anyone could help me out. When I'm logging the truck the injector timing seems to be dropping off on the top end, I am commanding 22 degrees but only seeing 17 on the top end. When it comes to injector pulse I'm pretty sure I'm trying to push my injectors to hard but I cant seem to get enough fuel on the top end. The modifications to the truck are as follows and I attached the tune file and a log from last night, any help would be greatly appreciated.

DDP 90hp Sticks
Arson 3 CP3 kit
FASS 95
Stock over s475 compound kit
Built Allison 1000
Head studs

Looks like you’re definitely commanding to much fuel, wasn’t allowing you’re pressured to keep up with what you were commanding. I made a few changes if you shoot me a message I’ll send you the tune if you’d like to try it
