Need help diagnosing this graph So i have been building my car slowly and finally got it ready to get a tune on it. I have a 383 stroker kit. Dart Pro 1 225cc heads. Cam is 629/611 lift with 230/234 duration on a 112. Stock rockers. 3.73 gears in back with a 4l60e tranny with a 3800 stall. For some reason i can not get the graph to upload; i will try again soon.
Basically The power curve flatlines at 5200 and the torque curve drops at 5200.
Also, the power only peaks at 357 and the toque peaks at 352 through a mustang dyno, which obviously is not right. Any ideas on if there is a problem or something not done right would be great. I know the tuner well, so i am pretty sure it is not the tune. Thanks and will try to have the graph up shortly

Your horsepower and torque always cross at 5250 rpms. It has to do with how torque is calculated from horsepower. Are your dart heads out of the box stock? I haven't seen very many builds using them and no results that seemed good. Being an auto you are not going to dyno high and being on a mustang dyno you are going to dyno lower.
