A couple things spring to mind.

You have had the car dyno tuned with this setup, right? Seems like it would've blown up if not, but you didn't mention it.

Knowing what can is actually in it would go a long way to figuring out how it's supposed to behave and how it might play more nicely. In general yes, a cam that is wildly aggressive on a smaller displacement engine is going to be a bit nicer on a larger one, but it won't be a night and day difference between the stock displacement and a 416 build.

Also, take some pictures and some video of your ride, because god drat. :getin:

Importing them up to the US is a legal issue primarily. We can't import them as complete cars until they're 25 years old. But since we do have the G8 and GTO, there are companies that import the bodywork and convert them into utes so that they are still legally Pontiacs, not Holdens.

And yeah, there's a big difference between someone who can just get it running safely, and a proper tuner that can actually make it run well everywhere in the range. The latter takes a very significant amount of time, even if they have a good baseline to start with (a tune for a car with the same engine and mods as yours).

It sounds like it can be tuned to be more docile for daily driving, while keeping the cam in it though, so I'll give that a go.

It can definitely be tuned to be better, but "how good" is going to depend on the cam. Even the LSx has its limits where a cam is not going to behave below 1500RPM if it's a stupid big cam.

Mods: can I start an LSx megathread type thing?

Sure, why the gently caress not :getin:
