There are a number of things that can cause what you are describing, but most of them will usually set a code. Without more data, we don't even know which direction to tell you to look. Do you have a way to datalog the truck and post it here?

Can a autocal v3 work

Yes. Download EfiLive and use it directly or use it to set up the V3 for BBL
