once i got home i looked at the tune the guy did and looking thru the maps he only adjusted the ignition map and fuel map

the o2 map havent been changed or messed around with at all as soon as my a/f gauage arrives i am going to install it and see how the AFR look! car runs up until 5000 rpm where seems to lose of power from fuel
and garm i asked him wat my duty cycle was and he just gave me an example about how at idle they may use .8 volts and at full throttle they could be using
3 volts and injectors arent the way to go it is better to ungrade fuel pump so
that when the injectors are opened it would squirt more fuel into the engine when the injectors are open

Ok I didn't see this before. So it was a dyno dynamics, as I suspected.
Also, from the dyno graph.... Full boost is 6.5 psi, not 8. Those hp numbers are good, don't let anyone tell you otherwise. 150whp on that dyno bends rods. The voltage description you described is most likely the MAF voltage table, which is not related to duty cycle. Only thing I don't like seeing on that dyno sheet.... Is the fact they never calibrated road speed to
RPM, so I don't know how the tuner knew where to make fueling corrections accurately. That sheet also is labeled as " run file 009" , we have never been able to tune a car in just 9 pulls.... So that is suspect. Unless they purposely stopped tuning because they were not comfortable with the fueling.
