That's the "Stair Step" acceleration.  Its like they had fuel delivery 
ranges, and did not extrapolate between them.  Ned from Intended 
Acceleration told me that the chip smoothens that out.  I'm thinking 
about buying one.  My V8's hesitation problem got better when I used 
some injector cleaner, and it got better on the drive home from picking 
it up when I filled it up with premium fuel.   I suspect that the 
previous owner used regular gas.  It still does it occasionally though, 
and sometimes it seems like I'm losing about 50 hp.

Mine idles great.  It starts very well, and idles very smoothly and steadily.
