International navistar software your experience

Looking into buying legit navistar software like navkal and hero, maybe on command. As much as i hate maxxforce, they are popular truck here in Detroit and alot of my customers are buying them.

I have texa which is awesome, but id like to be able to flash modules like the ECM and ACMs and could use some extra help diagnosing the data network.

Should i pull the trigger and buy the bundle? I really dont see how anyone gets by anymore working on a truck with 7 different computer modules without the state of the art software .

My father runs the shop and i dont wanna look stupid so any input is appreciated.

 

Ive already bugged heavy D hell in high heaven lol. Im basically buying this software so i can flash a ACM on a problem child job thats been in my shop since Christmas.

 

Thanks heavy D. I was reading the interactions manual on navkal and im pretty sure i seen flash ACM option. Your insite is the best on the forum. Had to save up for a nexiq 2 connector. My texa one wont do flashes

 

There stock navistafz

They are stock and i dont wanna talk about the Evil D word because i dont wanna get banned from this group

 

Is there anything ill need for the body controller?
