Default Mail order tuning, swap harness

Hello, i have a question i asked in the conversion section and did not get an answer. Im looking for an aftermarket harness and computer with tune. Is there a single source for this or do i need to purchase separately? Also who would you guys recommend? Its a 5.3 with a summit stg 2 truck cam, stock everything else. Thank you for your help.

psi for the harness. I've done my own, bought cheapie china ones, bought professionally thinned stock ones and the only time there were no issues whatsoever is with a couple psi harnesses

my .02 cents

there are some very experienced vendors here that could likely nail a tune that basic via mail order.

I emailed PSI yesterday, waiting for a response. They offer a computer with "programming ". Im not sure what that includes. I will hit up a few vendors and see what they say.

I would get a harness from psi and source the tune from someone well known. Someone like nelson performance, frost, or lsx power tuning etc.
