Default Best tuner for a LB7?

What's your opinion on the best tuner for a stock LB7? I have been looking into edge evoHT. Has anyone had any experience with that tuner good or bad? And also if I were to purchase this tuner would I want to get some gauges?

EFI for THE BEST possible tuner

I have no experiance with PPE, but I do have experiance with EFI live. EFI is fantastic you can do crazy stuff with it. That is both a blessing and a curse at the same time. There is lots of tables that do lots of things and that being said if done right awesome, if done wrong well not so awesome. There are lots of people that will help you through the learning process and it is steep (for me any way), You can spend hours working on tunes only to find out after someone with skills reviews it that you had made a tune to do nothing more than put holes in your piston.

The data logging you can do with it though is awesome once you have your pids set up with what you want to log.

If you are looking for on the fly and dont want to mess with tuning Look into getting a dsp 5 and then buy tuning from your favorite tuner. I have APT from an older set of twins on this truck and Lets just say it moves pretty good and the truck will light up the 35's at 20 to 30 mph in 2wheel drive. I have other tunes from other members that were trying to help me trouble shoot that lets just say they move too. I did zero changing to these tunes.

If I butcher the next part of this sorry. I recently had a tune I liked but had issues and Cummin_Un_Glued a vender on this site Torque T Diesel. He helped me out with it and not only did he fix my lope problem he smothed out power delievery and the smoke is almost completly gone and will **** off some new New Mustang and SS owners. Larry Jewell has also helped me out alot.

^^ 2x what he said. EFI Live all the way

i had another for a while and got efi live, i will never use anything else now

it does have a learning curve but you learn so much about your truck and what the ECM is doing, that it is well worth it. most venders will provide a tune with the purchase to get you started.

my vote = EFI Live 100%

How do you go about getting a EFI Live Programmer do you have to get it direct from a vendor? I can't find anywhere to buy one on the internet. I found PPE programers. The say that the top of the line model boosts HP up to 400 HP. Is that True? That would make my bone stock LB7 at about 700 HP theoretically. Is that how that works or do I have to put other mods on. Also I was wondering if I need to think about any other mods before I put in a tuner. I have a AFE intake. I don't want to blow anything up.
