Allen Nelson hands down. He can create a custom tune for you that is far superior to any canned tune. You can purchase HP tuners software if you want to make tweaks yourself, or just have Allen tweak it for you and send you a new pcm. Did that kit come with some sort of fuel pressure booster--a fmu or an extra fuel pump? didn't see you mention that very important part of the system.
