Default Mail Order tune (HELP NEEDED!)

I am looking for a tuner to work my PCM for me alittle bit.

I have a HP Tuners pro kit; and I have the PCM that was pulled from the truck with the 4.8 motor.

The 4.8 has twin turbos, ls2 Cylinder Heads, PAC 1211x Valve springs, ARP head bolts, Ligtenfelter HP/HV oil pump, LS7 lifters, CompCam Pushrods, LS9 Cam, LS9 Head gaskets, and front cam sensor conversion.

It originally came with a 4l80 bolted up,

the truck its going into is a 2000 Chevrolet 2500 originally with a 5.3/4l60 setup. The 4l60 was JUST rebuilt about 200 miles now.

I would like to keep the 4l60 in the truck with the new motor until it goes atleast..

SO my questions, Should I use the PCM in the truck already, or can I use the PCM from the LR4 4.8 liter? Or does it matter?

I am looking to have a tuner go through my PCM, setup the trans, setup all the timing, and fueling for the boosted setup, and also run it o2 free, and use HP Tuners to run real time tuning.

I can unlock the PCM with my HPTuners if you want, or I can leave it for you, I dont know how affiliations work with HPTuners, if I can use it on my software after you unlock ECU, or visa versa.

I will start reaching out to various tuners i can find, but i was hoping for some experienced expert advise that could lead me to the right tuner I am looking for.

Thanks

Since you'll be using HPTuners, have you already licensed the existing 5.3L file/PCM? If you have, Id keep it, change the displacement to 4.8 and upgrade to a COS.
