Very impressive for a single pump!

Correct, but I would be more worried about injector timing over BSFC unless the flow really goes to shit up top.

Fuel consumption will change with airflow demands and rpm. Higher airflow=more fuel requirement to maintain the same AFR. Typically peak BSFC is near peak torque rpm and a little under WOT for throttle. There are some good reads on the topic on google, particularly the engineering forums.

You definately need more injector to make the same power at a higher RPM. The more RPMs, the less available time an injector has to fire before the next revolution.

word. I think it is hard to find a DSM that is not rewired at this point.
