As a point of comparison, his output is 26hp lower than Stillen's advertised output. However, making the same comparison with te GTM kit, the best output is 62 hp lower than advertised. I say that based on Shumby having the highest output at 390 hp and GTM's claim of 452 whp. If you have other figures, please post the link to the dyno chart because I can't find any other dyno #'s from other forum users that have the GTM kit.
