Where to get it tuned: Hybridynamics. Even if you would get Crome.
I can’t remember cost or anything. I’d get the S300. I have the S200, but that’s all that was out then.
I can’t complain about the system at all, but I don’t do my own tuning so I don’t know that side of it. Runs smooth, no hiccups, and it hasn’t been on a dyno for 2 years.
