His power curve is the bottom line before 5000RPM and goes to the Upper line past 5500RPM. The other line that peaked at 4900RPM is his TORQUE curve which becomes the lower line after 5500RPM. So his Max Torque peaked at around 4900RPM and his Max power looks like it peaked out at around 6700RPM before he leaned out like crazy!
Definately find another shop and get your retuned man, that is some f*cked up A/F curve!!! If you get your A/F to around 12.0:1 all the way til redline, you will also see a slight increase in power towards redline.
