Induction parts + ECU reflash dyno results

eXo5

whats the diff between a reflash and a tune? The only reassuring thing to me on looking at these graphs is that the reflash helps with low end torque loss with these parts.

Reflash is the term for what is being done. You have to flash the memory on the ECU.

You're talking about the difference between a Base Tune, and a Dyno Tune. A Base Tune is an off the shelf tune that was done on some other car on a dyno. If your car isn't exactly that car, then your gains will not be the same. A Dyno Tune is your car specifically being tuned.

I agree with original poster that a supercharger is the only way for us CA people to go. I have a bad temper and if some cop wants to take my TT370 I would go ape chit on him. CA does suck with all its laws but hour and a half to the beach or the slopes isnt bad.

ok I just read all of that and all i can say is we really need to have a process for just going in and indiscriminately just deleting the last four pages.

Other than that I picked up the same stillen headers for $470 shipped, I have some $300 test pipes lined up, and i have some extra throttle bodies I'll be using as cut-outs from there and doing some muffler mods(free). So you can either call that ~50hp for < a stack, or just that I'll have 4G's left to throw into suspension which won't add crap for hp. Oh and I can install all my own parts.

Edit: found the same ss304 test pipes for under $200

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.
