Induction parts + ECU reflash dyno results

I didn't want to start a new thread on this so I figured I piggy back on this thread..
I have a 2009 370z Touring with Sport. I installed the Stillen G3 intake, Stillen HFC and Stillen CBE..Now is an ECU tune absolutely necessary to get the full benefit of these bolt ons?
Man, I'm so freakin confused with this stuff! Yeah, I'm a total rookie! I just got into this modding and man, it's so addicting! I don't know what to do next. Anyway, I hope I didn't piss anyone of you off with my rookieness!

I'm confused also on these cars and been doing this literally for decades so don't let a rookie status be the excuse. Everyone is a rookie in the grand scheme as they're complicated buggers and new to most everyone.

Gonna say yes and no as to do you absolutely need it tuned. Regardless, you're going to see gains, it's just a tune is like shining your shoes. It optimizes basic engine principals like air fuel ratio, engine timing and lets you set your own parameters for things like speed limiter, rev limit, etc.

Problem is the ecu has been a hard nut to crack and the true tuning capabilities is still a black hole. The honest answer is no one really knows.

Thank you very much! I appreciate the response. Guess I'll just stand by and continue my education on this.

I totally understand where your coming from. I'm a rookie when it comes to mods as well. I'll be putting in the Stillen G3 intake soon. I think I'll hold off after that for now. The problem with trying to educate yourself reading these forums is all the different opinions provided. Trying to sort through whats BS and whats usefull can be difficult sometimes.
