manifold advice?

I made 265 whp at 21 psi. I can email somebody the log if your interested. I thought the numbers were pretty low, but the guys at the shop said it was what they expected. I was pretty skeptical so instead of bitching about it I was planning on upgrading a few things and getting it tuned at db on e85
