Specialty-Z does it again with the charts to back up their products. Am I reading it right that member WXY's car is running stock turbos, boosting 21PSI, maxing 450HP, and hitting 300HP before 3,000 RPM? WOW! I wonder what it could do with MS manifolds…? Thanks to Greg and Seb for serving the Z community as you have for so many years. I love my SZ turbo back exhaust!
