370-380whp on a dynojet is typical for a bolt on car depending on conditions. Show me one plot on pump gas making over 400whp on a dynojet and I'll give you a cookie. Hell, you can even browse the dyno compilation on e90post.com and see for yourself. You won't crack the 400whp with a jb4 or procede unless you run race gas or meth.
