If not he needs to know to keep the runs short , a long run makes lots more cyl temp and will not give any different hp or mixture readings, compare the run to a 4th gear blast, your only on power for several seconds .
Air/fuel ratio needs to be ~11.5 on boost no leaner than 12:1 esp with the usb as there is no timing control .
Use fresh premium 98 even add some thing like bp racing 100 at 50% .
do not exceed 8 psi boost
If the part throttle transition is not smooth the fmu is set incorrectly.
Good luck
we are running 6lb boost
