I'm currently in the process of building a new engine for my FBody I cracked a piston in my 5.7l. so I bought a new 5.3l bored to 5.7l iron block. was curious on a mail order tune. because ive bought a heads/cam package from TSP, have headers going in. and eventually a intake and injectors to help out with the cam and heads package later on when I get the engine running and find the money somewhere.
who do you all recommend for mail order tune. ive heard TSP are good. but curious for the people who have built engines and done this multiple times.

Mail order tunes should not be an end all be all tune. Sure sometimes a vendor can nail a tune 100% and get lucky. But nothing replaces having the vehicle there in front of the tuner on a chassis dyno so they can watch all parameters and really dial it in. I would say get a mail order tune to simply get you on the road and then take it to have it dialed in on a dyno.

That's what my plan was originally. Because where I live there are 0 performance shops. So I was just going to use the Mail order tune until I find a shop I trust to do a dyno tune

My opinion is that you should go directly to a dyno or street tune. You can probably do all your mods and drive to the tuner, swap your injectors there and have them adjust for them and tune, that's what I have done several times.

we have a sponsor who can do it. LSX power tuning

TSP and LSX power tuning can both get you a mail order tune to work had good interactions with both of them.

Which is best bang for the buck?

Mail order tuning can work if you have a wideband and can take logs. It just takes longer than doing it in person... but it's the same as what a tuner does in a street tune. They set a baseline tune, you got take logs with the wideband, and adjustments are made based on both your feedback and the data shown in the logs...
