Ok, so I have done plenty of searching on here but can't get a definative answer to my question.
I am thinking of making some modifications to the Z with the aim of getting a little more power. I have looked at 06 airboxes, performance filters, exhaust systems, plenum spacers etc. There seems to be mixed views around what these types of mods will actually do, with many saying the ECU will just cancel them out.
Is this the case for all of the above mods or are there some gains to be made?
I am not looking to spend thousands on TT and SC mods.
Is there anything under a Grand or so that can squeeze a few extra horses out?
