cab and chassis ????
 

Anybody know why you cant tune a cab and chassis ?

Same reason you can't tune a fish.

What are you asking? Cab and chassis? Why wouldn't you be able to tune it. The motors and such are the same as a regular cab and bed truck? So specify what exactly what you mean.

Well i was lookin around and i keep seeing this wont work on cab and chassis model i did find out they are a littke different with the ecm but idk i was just curious
