   16v engine few mods
   138bhp
   
   I'm not worried about the figure
   More bothered about the graph and lines
   
   Does it look like it's slightly overfueling?
   Lambda change do the jOb?
   
   Graphs
   Anyone fancy telling me what to look for in a good graph figure?

   question:
   WHich line shows fueling?
   is it suppose to be fueling up in a slow line or how can you tell?
   
   could it be the rollers that are crap or if what on car?

   First graph on your post show the feuling line. Should be alot smoother on full throttle.

   lambda? map?

    the fuelling graph is wiggly because of the sample rate --the data logging speed,if the sampling rate per second were slower it would be a smoother line

    it's wiggling between 12.5 and 13.6
    
    There's room for improvement, certainly a flat 13.1:1 from 2000-7200rpm would be 'better' but you're inside the window
