cali model question
 

I'm sure this has been gone over, not handy with the search function... my truck is an 04 with California emissions 235hp. The dealer in my area said they could flash it to the 305 h.o. my question is if I flash my cp to 305 will my banks 6 gun still add power to the truck? Sorry if this is a stupid question.. fairly new to the world of common rails. Thanks

That is not a stupid question
I'd say give banks a phone call and ask them if it would still work.
Go right to the source.
