Funny, he says he can do an Emanage tune, but can't quote accurately, so I take it that means he hasn't.
Haltech option is a new unit which works with 350Zs, so they figure it'll work with VQ25s using the same trigger pattern. I have a quote for $500-1000, but no guarantees it'll work.
Seriously considering getting Cian to do it when I come over for Gymkhana World Tour...
