it's pretty hard to determine dyno graphs from different days unless it's in a controlled environment with the same barometer readings/air temp. oil temp and water temps all being the same. the d.t.s. dyno we used would correct everything to "sea level" conditions along with the "as is" test conditions. I have seen H.P. change as much as 20-30 H.P. when the air gets good, these are on 437 ci. Hemi super stock engines making over 900 H.P. A small motorcycle engine 800c.c. could vary 3-4 h.p. under good air conditions or "below sea level"..your best performance gains are going to be from acceleration testing, how quick the engine gets to "peak horsepower" I have seen many times engines that make less dyno horsepower blow the big horsepower engine in the weeds..because they accelerate quicker...it happens a lot in nascar and N.H.R.A. pro stock racing. the dyno is just another tool, in the end.. the race track is the real dyno. all professional engine builders and racers will tell you the same thing.

If your phone isn't ringing..it's probably me!...
