I'm a little unsure of what root I want to take with tuning. Before I plan on a tune, I will have an intake, plenum spacer, HFC's, and cat-back. I still have a S-AFCII that I used with my Supra, as well as a wideband O2. I'm thinking of using the S-AFC, but from searching it seems it is not a very good piggyback for the 350Z. My other thought was a reflash. I don't really have the money for a UTEC, and may also start spraying in the future. Do you guys think I could use the S-AFC? Or would the reflash be better for me?
