My lb7 is completely stock besides 4 inch mbrp straight pipe. i want efi live but dont want to blow my tranny or motor. I mostly just want a smoke/lope tune is some small power tunes. what should I do to my truck to have efi live?

 

You dont have to do anything to your truck, tuning is customized to your trans as well. It works wonders on stock trucks too, I would get a CAI since Gm's are notoriously restrictive.
You can update tuning as you upgrade the truck

 

okay, I just want a tune with alot of smoke to play around with and 4 power tunes. do I have to get a built tranny or a shift kit?

 

Most legitimate tuners are not going to give you what you are referring to as a smoke tune. At the end of the day they have to put their name on the tuning.

 

But can I get one that will produce smoke? And what do I have to do to set up efi live on my truck?

 

I tune for EFI that produces smoke is called a "Race" buy most tuners. You can get stock trans safe tuning that will produce some smoke by most tuners. And that would give you like a optimized stock tune, light tow, heavy tow, Sport Econ, and a Stock Trans race tune

 

okay, what is the highest hp tune I could get with a stock Allison 1000? and how much smoke would the race tune produce and would it ruin the head by blowing smoke?

 

100 over stock roughly but constant abuse will shorten trans life. It will produce some but not black out the sky type deal. And as long as you dont go beating on it like a red headed step child you'll be fine.

 

okay, all I pretty much want is it to blow a good amount of smoke when I want to smoke out my buddies and stuff. what do I need to run efi live on my truck? like do I need a computer and how hard is it to install?

 

Id do a full drop in ecm or auto cal. Or you can buy a v2 with licenses and buy tunes seperate. The ECM or AutoCal are 5 times easier that the v2 route
