Im not sure if this has been covered, but I didnt run into anything regarding it. Im curious to see if and what tuners have been encountering with the FI kit tuning on the various years of the Z - more so related to the changes to the VQ and ECUs over the years....such as:

03-04........Default
04.5-05.....ECU/Wide Band 02 change
05-06........REV UP Motor (VTC for exhaust -tuning/physical space (though very minimal-any possibly fitment issues)

Thanks in advance.

No issues yet, in terms of tuning or installing on the various models. Keep in mind, that Vortech SC's will not work on 06 or 05 Rev up motors, until Vortech redesigns that main bracket.

Just to let you know Vortech has been hard at work with redesigning the brackets... Honestly they should be done with it. They mocked up the brackets on my G35 sedan and were installing a kit on a Coupe last I heard and that was about 2 1/2-3 months ago. So I'm sure they have a few running around with a kit, they are probably just R&Ding the tuning.
