With the intake and exhaust the car runs way lean in the midrange and way rich up top. I installed the apexi vafc to adjust open loop fueling and vtec crossover. It worked great for a while, then started having a noticable dip in power coming into vtec. I've un/reinstalled several times and redone the tune, but it just keeps acting up. For now I removed it, and I'm trying to decide if I should just go back to stock, buy a better tuning solution, or of course there's always a ratty old miata that's catching my attention that I could just replace it with.

I made it out to the dragon today and made a few runs. It was cold so I didnt go too wild, but made some runs with a friends 350z.
