Default Stand alone wiring and engine internal changes

Hey guys I've got a 4.8 gen3 truck engine which has the green pcm plugs ,I've also turned the 4.8 into a 5.7 iron ls with tbss intake and 4l80e box .I am wondering do I buy a standalone system that suits the 4.8 or 5.7 or do I just need to suit the green pcm and have it all retuned once in the car as it's a conversion that's been done into an older car tia 😊

I have a biased opinion, but going with the Holley Terminator X Max ECU will give you a lot of flexibility. What kind of vehicle is this going into?

Since you are in Australia, this is probably a better option due to the fact that there are many competent tuners in Australia that know Haltech:
