9901 has crazy top end when its used with the right manifold ! your issue is you simply used the 41021 and called it a day...swap to a 41001 and that 9901 will put a big hurting on a 2096 ....the 9901 has a crazy good top end when it has the right manifold ! it just doesn't like the 41021, that manifold murders its top end
