I'm Awesome
One thing to note, and please correct me if I'm wrong, but your 0411 was direct from lextech with his "base tune" correct?
I do believe that lextech has his tune for the 5.7 dialed in quite well, so 2500ss could probably run his base tune as is without issues (speculation). A couple of his "base tunes" for the 454s that i have looked at need some tweaking. IMO pay the extra money and get a tuned 0411 from BB, UNLESS you are planning to buy software and tune yourself.
I do not mean this to bash lextech in the least, he pretty clearly states that his tune is a "starter" tune, which i read as requiring tuning after the swap. The work he has done and still does is a great service to those of us that want better computers.
You're correct, it was the "base" tune for a Vortec 454.
