I'm getting 6080 RPM static.  I could only get about 5800 or so, then 
noticed that my Manifold pressure bounced around plus or minus about 1.5 
inches.  Tracy changed out one of the sensors in the EC-2 that may or 
may not have been a problem, but the big thing was to dampen out the 
pressure going back to the EC-2.  It is almost rock solid at any Map 
now. I restricted the lines way down for a couple of inches then it runs 
into an accumulation chamber about 2 inches long filled with tightly 
rolled up scubby green pad.  I think that the pulses messed with the 
brain of the EC-2 and it didn't know exactly where it was as pressures 
to the sensors were many several times a second.  My field elevation is 
5000 ft  with a Catto 76/88 with the C model PSRU and a stock Renesis.  
Also play with your mixture.  Try turning it a little leaner!
Hope this helps.
