350z ECU question

[maximus108]

hi everybody!im new here...I wanted to know when it would be time fora ECU reprogram/aftermarket ECU?If I change the intake, header, exhaust(aftermarket) will I need to take the Z to the dealer to reprogram the ECU?Or would it just be better to get an allnew aftermarket ECU? Thanks

You should be fine with adding those. It you want to maximize the performance you could buy a retuned ecu.

Yea you should be fine to run on the stock ECU with thos small upgrades, but there is little ECU flashes that can be done to the Z's to get a quick 15hp.
