Disappointing dyno numbers?

My motor blew last year so I sourced a replacement and swapped it. I'm running a comptech SC novi 1000 with 3.4" pulley, E85, 1200cc injectors, Walbro 255. I was expecting to at least be in the high 3's. My tuner said that my rising rate regulator was malfunctioning so I will have to purchase a new regulator and retune. He said that we can push more out of the tune when the fpr is replaced. Even still, 330hp was disappointing to me. Am I being unrealistic? I'm not the biggest car guy so let me know if I'm being unreasonable.
But at 7 psi down at Erik's racing on dynopack I was at 417hp. How is that possible....
We did a baseline at vlspeed and at 7 psi I was 230whp. How is that 417 on dynopack. I don't know. I trust dynojet more. That's true wheel horsepower.
There's no way all these kraftwerks are making 420 true whp.. ...

The OP said he was using the rising rate fpr. You do not want to use this. This is for stock/stage 1 set up only. You now have large injectors and an ems. You need to put the stock fpr back in for a good working proper static fuel pressure to tune around. Your tuner should have enough experience to recognize this. if not, look elsewhere.
On the 3.4" pulley at sea level you should expect to see 11psi ap2 or 12psi ap1. 360-380whp is typical for this blower at this pressure with a proper good tune.
