For anyone who is concerned about live vs. emailed tunes, I have a LB7 and I have an LBZ, so as far as stock truck/live tuning unless you have a unicorn I have a tune for you as well as access to LLY and LMM trucks and even other LML trucks.
I have sat in no less than 300+ custom built trucks over the last eight years and there is not a combination I have not seen or tuned at many elevations as well.
To comment on the issue of locked tuned and being a pain to make changes, you hire a professional tuner and lock your work down so that you don't have the owner in your tune playing around with tables, then calling you telling you something isn't right and then you have to go back in and see what they changed, plus it is intellectual property cannot be copied, shared, sold etc when you take steps to protect your work, because we know everyone isn't out to make a buck these days off someone else.
As far as boost issues and complaints about them, there is an issue with the VVT trucks which means if you ask for more boost at low rpms then the truck can deliver it will throw a P0299, in the case of many LMM's this will cause the Reduced Engine Power to display a message and sometimes cause weird issues.
So you can only give anyone what the truck can give you, you can ask it for a big boost number down low or up high in the rpm, whether or not it makes it is a different story.
Just like you can't get a TCM to start in second gear in just one DSP tune which I get asked to do a lot to do by sled pullers..............
Both Dustin and I are resellers and I travel to North Carolina at least every 6-8 weeks and will be there from this sunday thru next friday.
