A scope would be nice, but at least check the timing with a timing 
light.  Years ago, when I used electromotive for a few months, I learned 
to trust nothing.  The reason I asked about the RPM reading, was not 
only because of my experience with not being able to read RPM at 
cranking speeds, but also an article I read somewhere about the VECTOR. 
 The test driver noticed the rev-limiter was cutting in way before red 
line, and the problem was traced to the engine management system.  Guess 
what system they used? TEC!

It sounds like your injectors are way oversized for the application.  Do 
you know if they run sequential, bank fire, or gang fire?
