I saw a guy post on VQ|Nation Facebook page with Stillen sc G37 who pushed 452 whp and 398 wtq on Z1 motorsports tune. It's all in the tune. If you do it right you can reach 500 whp. I'm running 8 psi and Im about to upgrade to Eagle forged rods and Wiseco 9:1 forged pistons. Hopefully I can boost up to 500. Currently sitting at 414 whp on the can tune and I'm installing fb heat exchanger. Church is gonna do my tune.
