Dyno could be a factor, if they are dynojets that others are using and your running a mustang dyno your figures will be lower than theirs.

Also not all engines are equal from the factory, sometimes you've got a factory freak or a factory dud. I know for a fact that the engine I started with in my car was a factory dud, it made 105whp w/ intake, header, highflow and exhaust. Not very impressive. I know this is why I am substancially lower in HP than others running the same setup as me.

Thats why I was asking for maybe a before kit dyno, you could be in the same situation until you identify the problem.
