good pickup on the cams that probally part of the problem. Plus add about 10% for difference in dyno #s compared to a dyno jet and he's sitting at around 340rwhp now.
Going back to stock cams and a retune should solve the problem and get him very close to 400.

 

thank you enery body for your answer i will remove the bc camshaft and retune the cars so i let you know
