If you opt for the custom tune route, I can recommend Ted Jannetty up in CT, he is an absolute pro with decades of experience with LS and LT platforms, and a no-nonsense gentleman. See his shop at
www.jannettyracing.com, he does remote tuning as well.
He tuned my car with the Maggie 2300 and all the other mods (in stages) that you see in my sig, and it's near perfect. He even sent me a free tune update (without me asking) years after me purchasing their products and tune, simply because he wants to be 100% proud of his work and said he'd learned new things in the meantime.
