Southern Members - LQ4 silverado tune?

so i put this 6.0 LQ4 in my 04 silverado in front of the stock 4l60e trans sunday.

im running the 4.8 program in the computer
all 4.8 stuff except the long block.
drive by wire.

im very close to doing a mail order tune.
but i would rather have one done locally.

as you can see in these vids there are some BIG holes as of now in the rpm ranges. and i have to unplug the battery or ecm for bout 45 mins for it to keep from stalling under load.

does anyone know of any tuning shops prefer but not require a dyno in mississippi? i live in meridian MS.

thanks in advance.

after about 15 mins of driving almost all power goes away.

I don't know anybody in Miss. but Geoff@EPS knows what to do with that kind of stuff. He's in Baton Rouge LA if you feel like taking that drive.
