Manny from Pennsylvania had already dipped into the nines with our Purple Belt Performance Package. Some people would be satisfied there, but Manny has bigger plans. He shipped his car to us, and we installed our Stage 2 valve springs, titanium retainers and camshafts. Then we completed a custom dyno tune. Peak numbers were 635 whp and 668 wtq using SAE correction factor, which was 646 whp and 680 wtq with STD correction. Even more impressive was how the powerband produced greater than 600 whp and/or wtq all the way from 4,100 to 6,700 rpm! This is the beauty of our Stage 2 camshafts and world class custom dyno tuning.
