15psi

they don't boost that High stock do they?? I have seen a slue of them at the LVMS run low 14's. Even though they do make good power put a turbo on a CSVT and it would be a killer. Even if it was ran at about 10psi with a good tune it should have a much broader tq curve and much more cleaner hp curve than SRT4. Also one thing to keep in mind is the CSVT revs 1k higher than the SRT4. In a turbo application that means a world of difference.
