Yes it will make a huge difference. There is so much more electronically controlled too, transmission shifting and speed of shifts. It's like anything else dsp controlled. I can't stress the difference it made on a turbo. I'd hear it spool so much quicker and made the audi a whole other car. Like you expect straight from the dealer in a high performance car. Now, I know the z will be just that much better. For me, it made me regret money spent on other mods. I can predict it will want more intake.
