Flash or Tune?
 

So I've been trying to figure out if it is better to just Flash my ECU, or get it tuned? Maybe both? The car is a 03 G35 Manual.

You have to flash the ECU to get a tune. The question is whether you want to get a dyno tune for $600-800 and have 100% maximum performance or just get a reflash for $350ish and get 80% of the performance

So a Reflash would be where I'd like to go then.

Re-flash is a good start. I have a flash and a dyno tune. What mods do you have?

Go to my garage, and see them. Too lazy to type them out

You have enough to justify a dyno I think... But im always partial to doing those...

It all depends on your budget.. lol

true, but a flash is a few hundred right? Im not completely sure... I get my tuning done at cost because racecar/garagequeen

I literally just want a flash. And that's what i think my next thing is. Then a tune. Yet, you can not data log for a 03 G35 since it doesn't have wide band oxygen sensors

Well... That can be fixed....

That's an expensive thing too do.
