It was Dynojet. And as far as I know Stillen is the only one carb legal at this moment, but I didn't like the "look at me" hood. And HKS head of overseas marketing told me HKS SC already passed all carb requirements and now waiting for certification.

Negative, comrad.

 

Called Vortech last week regarding Carb.approval. Answer was, MAYBE within 7 months. Yes, Stillen is the only one for now. HKS and JWT turbo, is also claiming carb approved, when kit is released. Will see.

 

For your reference, there was one stock auto Z doing the HKS SC install at the same time as mine and tuned by the same person. His pre SC dyno was 230 rwhp and after SC dyno was 330 rwhp, compared to my G 214 rwhp pre and 298 rwhp after. Both were dynojet number.

Your tranny should hold up fine with even more power. I dyno'd at 360+ on a 03 5AT. I did need to upgrade my valve body. DFWG35 is pushing over 400hp on his AT coupe. Remember the tranny came out of the Q45 and M45 which make over 300 bhp so you're not too far over factory spec.
