It could be your fuel pump too.

Look at your timing too, if have to go through my logs, but I'm between 33-34 advance WOT at the top of my rev range.
Is that pulled back a bit with your tune to prevent overlap? |

Curious what would be the outcome if your car was running on 98oct with your 650kit? IMO you should get a slightly higher numbers with your kit as other have mentioned. Reason why i am asking is because your dyno result seems a bit low as i just dyno'd my car with a 625kit this past weekend there too and it was on around 98 octane( I would say lower octane) and got a better result compared to yours .
Okay, on the dyno day, I Had 3/4 tank of 91octane pump gas left and added aprox. 5 gallons of race gas to yield around 98 octane as the eas crew suggested. I wasn't looking forward to add any race fuel prior to the dyno then i recalled my car was tuned for 93oct as i used to live in NY, so I'd figured i would need at least some 93 or higher octane in the car in order to get most optimal result for the dyno, and it was to add some race gas or blends of E85. It was really a last minute thing. Nonetheless, I am very happy with the outcome. here is my dyno results of that day |

On a blend of 94-95 octane with no cats (MRF X pipe) I dyno'd between 575 and 583. On 94-95 octane with cats (Akra Evo) I dyno'd between 565 and 570. This is on 7.4psi boost at 8,600 rpm. I'm not trying to get the highest numbers possible. If I wanted to do that I would run full 108 motor octane race gas with zero ethanol content and install a smaller blower pulley.
