Tell your mechanic to start with BIG changes and narrow it down.Saves time since he will need to get a feel for it and is best if you can actually see results.Do him a favor and have your front plastic off,coil blue wire readily accessible for tach hookup.Dont forget tach reading is double until you blip the throttle so dont waste time trying for a good tach reading till you blip the throttle.Test the AFR by pinching the hose.Should immediatly pin the AFR reading.Do the runs in highest gear possible without stalling motor or if axle is bent use lower gear.Use slicks.Use one tiedown at lower shock mount on swingarm not the shock.Run other rear tiedown from the hook of other.If possible do not tie it down from bumper unless traction is lost and if it does you will know.Be sure IACV is closed before tuning.This can be verified on D&M.Concentrate on last line in map first.100% throttle then do 3/4 lastly idle and partial just useing AFR and not dyno pull.Throttle limiter screw can be used for doing some runs just above partial to ensure consistancy.Once as many position as time allows are done blend rest of map by hand at home the patterns will be quite clear.Move your Air Temp sensor to front of quad or at minimum away from any engine or frame heat.Run the dyno fans every run once its warmed up unless you are running Meth or E85.These will cool your engine without need for fans once enough fuel is added.
