Default finally some dyno numbers!

base run went 351hp/333tq with an off-the-chart rich a/f ratio... after a slight base tune with a few exhaust and vacuum leaks it went 365hp/ 350tq.. not bad for a little 224/230 cam im hoping to see a little more power after tuning.. the car is burning oil and hopefully the rings are ok!
