01Z28smith

Hello everyone thank you for reading. I have a 01 z28 with around 123,000 miles I am interested in putting a new cam and possibly heads on within the upcoming year I was interested in what plug in program is best for tuning a ls1 with said mods. The only bolt ons I don't have is a 90mm throttle body, that's my next buy along with Mac headers and ory pipe. I know the hp tuners are regarded as one of the best out on market now but I was wondering what are the predator tuners like I am currently looking at the predator 2 and predator 1 what are the main differences between these two tuners and are they able to tune in cam and heads on a ls1 if not does anyone know where to take a ls1 in Austin for a dyno tune?
