Definitely contact Topgunz about purchasing the A2A air to air intercooler set up or make plans to install a air to air intercooler set up it’s a much better choice as the air to water set up is inefficient. Since you are located in Northern CA look into Z Car Garage as they are not too far from you. You should speak with your tuner to see what tuning software they use and recommend. ECUTek tuning would be my first choice.

Yeah, I've been talking to Rob @ Z Car Garage. He did my suspension.
It sounds like an aftermarket tune is desirable regardless, which is kind of a shame from a technically legal standpoint, but it doesn't sound like California smog checks require validating the tune. I've read horror stories from other states rejecting tunes.
