power problem rotational velocity numbers with grey cps?

Some how after installing a new t500 hpop and multiple tunes I am having a power loss problem. Stock hpop beans tuner my truck went 15.005@89mph in the 1/4. Now with a t-500 and a reburn from beans best I could get was 15.6@83mph. So I switched to a dp-tuner and went to the track and ran 15.57@84 on 120R and 15.55@83mph on 100R. Icp on 120R is at 24-2500 74% duty cycle.No chip I can see a max around 2700 around 38-40% duty cycle. So my question is maybe the tunes are pushing my injectors too hard and they are soaking up all my high pressure oil? Any way I took a look at the rotational velocity and this are the numbers I got. PS running a grey cps

cyc1: 0.0%
cyc2: 1.6-2.3%
cyc3: 0.0-0.4%
cyc4: 0.4-1.4%
cyc5: 0.2-1.2%
cyc6: 0.0%
cyc7: 0.0%
cyc8: 2.0-3.0%

The numbers kinda jumped around a little so I took the highs and lows. Now beans said my pump numbers weren't band. I talked to Jody from dp today and after reading him my numbers he told me pretty much that on 120r that pump is giving all it can give theres not much he can do with the tune. Next I was told to check my injectors because I was told with no chip my icp should be around 27-2800 but around 25% duty cycle. So either my injectors are bad or the t500 pump I installed is weaker then my stock 17*
