Anyone modded their Z06 yet?

[Dgds88t]

I am thinking getting bolt-ons for my Z this summer (Intake, Throttle bodies and Sport cats). Has anyone here done the same? Do you feeling any difference in power before and after?

I am torn because some people say bolt-ons are useless without a tune and others are showing improved 1/4 mile time and 60-130 time.

Watch the dyno for the yellow Z06. You be the judge. Mid range gained quite a bit even without a tune.
I had done the 3 using budget parts than the yellow HTC. I will not be able to tell until summer. Plus, I don't have enough seat time stock to compare to modded. I will do the exhaust at the dealership this summer.
