I've heard lots of people say things like this. (Your thread isn't really "off topic" btw). The stock ECU is killing your bolt-ons. If you already have your Haltech that you're going to use with your turbo kit, get a tune now and you'll feel the unlocked potential of your bolt-ons.

Guessing its the bigger wheels, I test drove a stock Z as well as several with aftermarket wheels and there was a big difference in the feeling to me at least.
Also with those bolt ons a tune would make a big difference

Without before and after dyno you are trying to catch mice in the dark.

Try checking the codes. I didnt have a check engine light but I was throwing a knock sensor code. Changed out the knock sensor harness and sluggishness went away.
